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

Don't go borrowing trouble. For programmers, this means Worry only about what you need to implement.

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. ------ We are the carpenters and bricklayers of the Information Age. Don't go borrowing trouble.
