But in Python or ML, no question. I'd happily write a function that
returns (2, 4.2) without giving it much thought. Now perhaps cogent
arguments like "blech" and "belch" can convince me that I should
embrace the Tuple!(int,float) and use it everywhere, just like I'd use
tuples in Python and ML, but so far I'm not convinced.
To me it seems to be in the same league as int[] vs std::vector<int>.
int[] -- great I'll happily use that everywhere. std::vector<int>
kind of a pain, use begrudgingly as needed.
Well I think a language can only have so many built-in types. We can't
go on forever.
You don't have to. There are very few types that are extremely useful to
build up things having a good syntax. I think Python got this right:
tuples, lists, hashes. That's all you need as first class citizens
(speaking of "containers"). I think D is only missing tuples (dynamic
arrays works just fine as lists in D).
So we must add lists too.
