[ruby-core:39723] [Ruby 1.9 - Feature #5364][Open] How about new syntax: "object.\method" returns a Method instance?
From:
Yusuke Endoh <mame@...>
Date:
2011-09-26 03:38:21 UTC
List:
ruby-core #39723
Issue #5364 has been updated by Yusuke Endoh.
Status changed from Feedback to Open
Hello,
To prevent `bikeshed' discussion, we should focus use case first
about this ticket, I think. Why don't you talk about the concrete
notation after that?
I come up with some use cases. First case:
ary.map {|x| x+3 }
ary.map(&3.\+)
I like the latter not only because it is shorter, but also because
I don't have to bother about the name of the temporal variable.
We can already write ary.map(&:succ) in 1.9, so I think this style
will become more in demand.
Indeed, there is a trade-off between readability and writability.
I think it is a matter of getting familiar with it, though.
Another one for DSL. Consider rspec example:
lambda { foo.bar(baz) }.should raise(SomeError)
foo.\bar.with(baz).should raise(SomeError)
I think the latter is more readable than the formar.
I guess there are many possible use case in this field.
Finally, use case in future.
Ruby's Method class is poor currently.
I believe this proposal will encourage us to enrith Method class.
For example, I often use Object#method to glance over an unfamiliar
library:
irb(main):001:0> unfamiliar_obj.methods - 0.methods
[..., interesting_method, ...]
After I find an interesting method, I also want to read the rdoc
in similar way:
irb(main):002:0> unfamiliar_obj.\interesting_method.doc
Of course there is no Method#doc currently. I think this shorthand
notation will enrich such a feature.

Feature #5364: How about new syntax: "object.\method" returns a Method instance?
http://redmine.ruby-lang.org/issues/5364
Author: Joey Zhou
Status: Open
Priority: Normal
Assignee:
Category: core
Target version:
I'm afraid the normal way of creating a Method instance is circuitous and a bit hard to write:
a_method = object.method(:method_name)
I find the way of obtaining a function/method object in Python is so easy, for example, "str.split()" returns a list, while "str.split" (without parentheses) returns a method object. However, parenthesis in Ruby is always optional, so this road is blocked.
Well, how about "object.\method" style? You can type "str.\split" to get "str.method(:split)".
The reasons are:
1. It makes people happy, writing less code, and no harm to readability.
2. "\" is not a frequently used token. It can only be used in strings, regexps (or any else?). I think using this token leads to no ambiguity.
3. "\" is like Perl's referrence symbol. In Perl, you can use "$f = \&func;" to make a referrence to the function. In Ruby, "&" seems unnecessary.
4. It enhances the consistency of the language syntax. There are two correlative methods "Object#send" and "Object#method", but...
str.send(:split) == str.split
str.method(:split) == ???????
If adding this new syntax, it looks more pretty:
str.method(:split) == str.\split
