LL parsers love to parse the same text over and over again (though you can
prevent this if careful), but Perl uses an LR parser and resolves these
conflicts by looking ahead.
"{" is determined to be a hash constructor by looking ahead and seeing "}".
It would have to look even ahead further to determine a syntax error
follows that. I don't know how feasible that is.
