[ruby-core:67818] [ruby-trunk - Misc #10783] String#concat has an "appending" behavior

Issue #10783 has been updated by Antonio Scandurra. Tsuyoshi Sawada wrote: > I can't find the place in the documentation that says "Concatenation (aka= +)". Is this your own claim? If so, then that is not incorrect. I'll copy over the relevant excerpts. ~~~ str + other_str =E2=86=92 new_str Concatenation=E2=80=94Returns a new String containing other_str concatenate= d to str. ~~~ ~~~ str << integer =E2=86=92 str str << obj =E2=86=92 str Append=E2=80=94Concatenates the given object to str. If the object is a Int= eger, it is considered as a codepoint, and is converted to a character befo= re concatenation. ~~~ But then `concat` is defined as: ~~~ concat(integer) =E2=86=92 str concat(obj) =E2=86=92 str Append=E2=80=94Concatenates the given object to str. If the object is a Int= eger, it is considered as a codepoint, and is converted to a character befo= re concatenation. ~~~ I summarized what I had read in the documentation, therefore it was not an = exact quote.=20 ---------------------------------------- Misc #10783: String#concat has an "appending" behavior https://bugs.ruby-lang.org/issues/10783#change-51226 * Author: Antonio Scandurra * Status: Open * Priority: Normal * Assignee:=20 ---------------------------------------- Ruby String documentation (http://www.ruby-doc.org/core-2.2.0/String.html) = introduces the two terms **Appending** and **Concatenation**: - Concatenation (aka `+`) =E2=80=94Returns a new String containing other_st= r concatenated to str. - Append (aka `<<`) =E2=80=94Concatenates the given object to str.=20 However, calling `concat` results in an appending operation. I find this pa= rticularly confusing and against the Principle of Least Surprise (e.g. I'd = expect `concat` to actually concatenate something). On the other hand I und= erstand that changing such a small method would result in a quite significa= nt breaking change. Do you see this as an inconsistency? If yes, is there any particular design= (or historical) reason behind it? Thank you. P.s. Seems like this is the case for `Array` as well. --=20 https://bugs.ruby-lang.org/
