IIRC, the parser can only check the following token when deciding whether the { starts a block or an anonymous hash. That's also why the ; helps.

map{substr$_->[0],$_->[1]||0,1}[\*||{},3],[[]],[ref qr-1,-,-1],[{}],[sub{}^*ARGV,3]

    Perl could always try to parse a block and look if there is a comma following.
