In general, the idea of initialized doesn't mean a lot in Raku, at least not at the language level. At any given time, any variable has a value. By default, if you've typed a variable, it's initially set to the type itself (Any is the default type, so the default default value). The only exception

currying in perl6

I apologize if this has already been addressed, but given the following definition: sub make-adder ($a){ sub ($b) { $a + b$; } } make-adder 5 returns a closure, however pugs won't parse: make-adder 5 6 or: (make-adder 5) 6 I have to resort to: (make-adder 5)(6) Is this corr

A question on dev process then, I'm guessing that when a feature is added the feature and its testcase are iterated to perfection together? Comments and suggestions most welcome...
