Chill Eric ... it was just a question ...

If its an Activestate "trademark secret" then just say it ... no need to play around with words ...

Its was just my knowing urge ...

I find Activestate Perl interesting and wanted to go to the depths to know things ...

Take a chill pill, bro ...

You don't want to know. And really, you don't need to. You cannot reference a lexical variable by its name anyhow. For all you know, perl completely does away with the variable names at compile time, like a C++ compiler would.

And finally, it's not particularly relevant to any real aspect of perl programming. Compared to the amount of space perl allocates for everything else about variables (heck everything else in general!), the space that might or might not be allocated for lexical variable names is trivial, unless you had a bizarre contrived program with a million scalar lexical variables that went into and out of scope.

Lexical ("my") variables do not exist in the symbol table at all. Only package ("global") variables do.

Does the entry from the symbol table get removed for a "my" variable say my $var once it exits the block its declared in??
