Subject: [ruby-core:44266] [ruby-trunk - Feature #6265] Remove 'useless' 'concatenation' syntax


Issue #6265 has been updated by trans (Thomas Sawyer).


The only time I have found it useful is with `\` for multi-line string, for things like entry in Ruby based-config file. E.g.

    self.description = 'This is a multi-line' \
                       'description of something.'

Feature #6265: Remove 'useless' 'concatenation' syntax

What is wrong with this code:

some_method 'argument1', 'argument2' 'argument3'

Yes, the missing colon, but it is not always easy to notice that...

What is this ('concatenation' 'syntax') useful for?

Why writing ('some ' 'concatenation') instead of 'some concatenation'?

A missing colon between string arguments can lead to some bugs that may be hard to find, specially if the arguments are optional.

And I can't see any useful case where this allowed syntax for concatenation would help.
