$a->($b, $c) is just a nicer way of writing

&{$a}($b, $c)

but given how uncommon it is, I think I'd prefer it was a syntax error. I've
been bitten more than once by exactly the same type of problem as you.

I think with Perl 6 and the effort to ensure the maximum value from the
minimum amount of code, there'll be very few strings aren't a valid Perl
