Re: Variable Interpolation Interpolation

It's naughty to use symbolic refrences, but the way to do it is:

if ${"fromQuery::$f"};

Dragonchild, why is it naughty to use symbolic references?

Doing a search (which I'm too lazy to do) would yield some dozen or so threads on the matter.

A quick answer is this - symbolic references directly impact the symbol table. This could result in clobbering a variable you already have. As this is completely dependent on run-time activity, debugging this could be complex.
