I've run into the following problem using concat with Match objects from PGE. The code below performs a match, then attempts to concatenate a string with the results of the returned Match object:
There are several problems with the internals of objects derived from PMCs. The code tries to create a new destinaation according to the src operands (this is where the failing clone is called). If I turn that part off, it still wouldn't work, as it calls get_string on the contained Hash and not on the PGE::Match directly.
A workaround is to implement .sub __concatenate :multi(String, PGE::Match) and use the n_concat opcode (which creates a new destination result).
I'm also entering a todo test for the above into t/compilers/pge/02-match.t.
I've adjusted this test, to use this workaround.
Thanks, Pm
