Bug #2782

Binding#eval not completely indicative of its binding
Description
=begin
binding.eval("FILE") does not return the file from which the binding was created.
Given the purpose of binding it should hold that:
FILE == binding.eval("FILE")
=end

Just my two cents: (yen?)
__FILE__ is expanded at parse time directly into the parse tree. As such, it isn't really a variable or a constant, just a placeholder. I don't think it is going to be easy to make it act like a constant for Binding#eval.

In the current semantics, I guess binding does not includes
the imformation of filename and lineno.
At least, this is not a bug. I moved the ticket to Feature
tracker.

Sorry I was wrong. I didn't know 1.8 preserves the filename.
I agree that this is a bug.
And this ticket duplicates #1769. I've suggested a patch in that ticket.
