A method never takes arguments unless you use : or (), so those are all infix. The design team worked Really Hard to get rid of that particular ambiguity in Perl 6. Argumentless methods parse more like variables than like functions. Incidentally, this is why all the optional arg functions that default to $_ turned into methods, so you have use .print if you want to print $_ by default. Unlike a bare "print", a ".print" doesn't expect more arguments unless you put : or (), so it simplifies parsing greatly. Larry
