Subject: [ruby-dev:46916] [ruby-trunk - Feature #7639] More freedom for location of comments


Issue #7639 has been updated by sawa (Tsuyoshi Sawada).

Allowing a line to start with a period was a change introduced in Ruby 1.9. It is not what I am newly proposing here. If you are against it, that would be a claim against that feature introduced in the past. My proposal is, provided such feature was introduced, trying to make maximum sense out of it.

Feature #7639: More freedom for location of comments

=begin
When we chain methods with the period at the end of each line, we can put comments in between the lines:

    [1, 2, 3].
    # First, we do blah blah
    method1.
    # Second, we do blah blah
    method2.
    =begin
      Third, the following line
      does this
      and that ...
    =end
    method3

but when we have the period at the beginning of the line, putting comments in similar positions returns an error:

    [1, 2, 3]
    # First, we do blah blah
    .method1
    # Second, we do blah blah
    .method2
    =begin
      Third, the following line
      does this
      and that ...
    =end
    .method3

    # => Error

It is confusing that putting comments between lines in a method chain is sometimes allowed and sometimes not. I think it would be convenient if comments are allowed in these positions even when the following line starts with a period, and I request this as a feature. Currently, it returns an error, which means that, if such syntax were allowed, there would be no conflict with the existing syntax.

Furthermore, putting the period at the beginning of a line is suited for method chains because the period will visually work as bullets, and it makes more sense to have comments right before those lines.
