Re: O, the horrors of references and complex data structures

I know I am new at all of this but couldn't you just undef(globHash); before you start your next iteration? CiceroLove

Nop, that undef's the hash, so the reference he keep in AoH points to a now undef'ed hash. He somehow need to disasociate the %globalHash name with the actual hash. Basically two ways of doing that if he wants to keep %globalHash truly global; using local or messing around with glob's `sunw287 ~ > perl -e '%globalHash=(one=>"two"); $ref=\%globalHash; unde +f(%globalHash); print join("\n",keys %{$ref})' sunw287 ~ >` [download] goldclaw	[reply] [d/l]
