[1nickt]: Hm well actually I guess it's not the trailing semi-colon that's at issue there, it's disambiguation between the ellipsis and the binary flip-flop
[1nickt]: Although the example given does not produce an error as stated, on my perl.
[1nickt]: perl -wE 'say for map { ... } 1..3;' # "Unimplemented at -e line 1" ... <c>perlsyn says that should throw a syntax error...
