Subject: [ruby-core:68576] [Ruby trunk - Bug #10987] [Open] Warning "warning “regex literal in condition” issued, even condition is not constant

Issue #10987 has been reported by Ronald Fischer.

----------------------------------------
Bug #10987: Warning "warning ���regex literal in condition��� issued, even condition is not constant
https://bugs.ruby-lang.org/issues/10987

* Author: Ronald Fischer
* Status: Open
* Priority: Normal
* Assignee: 
* ruby -v: ruby 2.0.0p598 (2014-11-13) [x86_64-cygwin]
* Backport: 2.0.0: UNKNOWN, 2.1: UNKNOWN, 2.2: UNKNOWN
----------------------------------------
The following program emits the warning 'regex literal in condition':

~~~
#!/usr/bin/ruby
while gets
    print if /foo/../bar/
end
~~~

It seems that the parser does not recognize, that the "if" clause matches the regexp against $_
