If you rework this as actual perl code, its even possible to do today, with no changes to the perl parser. Really though, Limbic~Region should just be using lisp if he wants to have such flexibility. If this is too much overhead, the ifonce() function could be inlined like I described in my other node.

sub ifonce {
    my ( $test, $block, $else ) = @_;
    if ( $test->() ) {
        $block->();
        # Perform the appropriate B magic to remove this function call
+ from execution.
    }
    else {
        $else->();
    }
}
