Ummm... 
unless (exists $configs{image}{attach}{$text_to_check}) {
    # Do stuff here with $text_to_check
}

    'Fraid not. That would have to be done at the interface level, which would end up requiring said tests to be written into a dozen modules. I'm hoping for something which can be written into the same module as the $configs is defined, and thus can be used w/o editing the interface layer.

    Thanks for the try!

      You can do a tie to $configs, so that whenever a FETCH is done, it checks for existence and auto-vivifies before returning the value.

        But will it automatically give it a value that depends upon the variable it was called with?
