(Operators) postfix .:<prefix>

An operator in prefix form can still be called like a method, that is, using the . postfix notation, by preceding it by a colon. For example:

my $a = 1;
say ++$a;       # OUTPUT: «2␤» 
say $a.:<++>;   # OUTPUT: «3␤» 

Technically, not a real operator; it's syntax special-cased in the compiler.
