in thread Regexp substitution using variables

depending on whether or not $flags =~ s/g// succeeds

Testing $flags =~ /g/; is simpler.

    Simpler, but doesn't quite do what I need. I want to supply the remaining flags, once g has been removed, in the (?$flags:...) part of the expression. And I need to remove the g so that I don't get flooded with noisy console warnings about how it's being ignored.
