Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

I've exhausted my knowledge! Why does the first assignment to pkg1 work and the second assignment to the variable (pvar) not?

note that the "+++" print shows that pvar is the variable pkg2::VAR. i just can't assign to it.

I thought i could have a "simple" variable represent the ${ $var . "::VAR" } construct. thanks
