[ruby-core:47660] [ruby-trunk - Bug #7042] String#=~ is not equal to Regexp#=~

Issue #7042 has been updated by stomar (Marcus Stollsteimer).


=begin
From the documentation for Regexp:

"When named capture groups are used with a literal regexp on the left-hand side of an expression and the =~ operator, the captured text is also assigned to local variables with corresponding names."

Of course, this does not really answer the question regarding the "why".

Regards,
Marcus

i found out that string =~ regexp is not equal to regexp =~ string
when you use named captures:

"6:15 PM" =~ /(?<hour>\d+):(?<minute>\d+) (?<pm>A|P)M/; p hour,minute,pm # works not
/(?<hour>\d+):(?<minute>\d+) (?<pm>A|P)M/ =~ "6:15 AM"; p hour,minute,pm # works

i wonder why is that so ?
