Bug #10987: Warning "warning “regex literal in condition” issued, even condition is not constant

[rovf (Ronald Fischer)]

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 $_

• Description updated (diff)
• Status changed from Open to Rejected

The implicit matching in a flip-flop operator is warned.
