I found very interesting this piece of code as an example for the \G pattern, but I noticed that x modifier was missing on each regexp AFAIK, but then tested if there was anything else I'm not awared.
Just as it is, it returns nothing on $pat. Then added the x modifier and got an endless loop!
I thought it was related to a note in perlre: "It is worth noting that \G improperly used can result in an infinite loop.", but a small trace using print "($pat)\n"; just before each redo shows that \G is always at the beginning of the argument, not after what was already matched.
I tried again removing pos() to see if that function resets the pointer... No luck!
Am I doing something wrong?
