Some key differences from Perl 6

NQP's goal is regularity more than DWIM:

• Subroutine calls always require parentheses (no listops)

• Only binding available - no assignment

• No list assignment

• No default runtime library (i.e., no builtin functions)

• No array/hash slicing syntax

• Type constraints not enforced

• No given/when statement (yet?)

• Limited forms of smart matching (type and regex matches)
