Yeah, very obvious …
Pretty obvious question, really.
Hmmm… no-one’s taken the ball…
I have two or three times now wished that Array#shift(n) was implemented.
(quickly checks that it’s not…)
As in:
x = [1,2,3,4,5]
x.shift # => 1
x.shift(2) # => [2, 3]
I can (now) sort of see why that might be a bit irksome - returning different
types - but in practice:
foo, bar = ARGV.shift(2)
baz = ARGV.shift
That would work under the specification-by-example above. I know I can use
#slice!, but #shift just seems so right.
