RCR: String#contain? and Array#contain?

ruby-talk
1

Every time I have to guess from memory whether to use "contain?" or
"include?" within arrays and strings, I always guess wrong (the right
answer is only "include?" BTW).
Since ruby typically allows multiple ways of doing things, consider this
a feature request to add contain? to both String and Array.

Any feedbacks to this idea?
Thanks.

alias :contain?, :include?

That's what you mean?

You might want to read the thread about the "in" operator on ruby-core.
Something like:
e.in? ary
e in ary
give more sense to me than any enum.method? e

True, though at times I would find it convenient to use the enum method,
like

strin.each_line { |line|
  if line.contain? 'abc'
    print 'yes'
  end
}

alias :contain?, :include?

Yep, but just not me having to do it :slight_smile:
