Why throw on overlong slice?

Haskell does it the same way:

Prelude> take 4 [1,2]
[1,2]

This is similar to julia first()/last() functions instead of slicing. And they don’t throw either: first([1, 2], 4) == [1, 2].

Actually slicing a vector in haskell is also restricted to valid indices, same as in julia: e.g. Data.Vector.
