(I have nothing to do with the design process, so this is just my take on it)...
I get the impression that driving these sort of decisions, is the
historical problem we've had with only `perl` being able to parse
Perl.
Syntax is getting tightened up a little, with the result that perl6
programs are much more easily read, with the intention of allowing
different compiler implementations.
Also, we can only know if $term contains a valid subroutine name at
runtime, and perl6 aims to allow very separate compilation and runtime
phases (and syntax errors need to be figured out at compilation time).
