Hello,
I agree with what you're saying. I actually have already switched to MatchData objects
rather than the $-variables -- for all the usual reasons.
So, while my initial question may be less interesting now (since I have working code), I'm
still curious why in the statement
arrayList<<{"type"=>$1,
"param"=>$2,
"dimlist"=>$3.split(/\s*,\s*/),
"name"=>$4,
"description"=>$5}
operation on $3 modifies $4 and $5? (And, similarly, operation on $1 would "clear" $2 to $5)
Based on your first sentence, I guess I have an updated question:
Does using the split method on a $-variable count as a "regexp operation"?
cheers,
paulv
