Re^2: schwartzian transform problem - Solved

[Cristoforo]

Hi JohnGG, I'm trying to follow your solution using the GRT sort. I wonder why you have m{(\d+)(?=%)} where I might have used m{(\d+)%} without the positive lookahead for '%'?

There's no difference since $& and others aren't used, but /(\d+)%/ should be faster.
