Str\split should return remainder independent of parts

[rob0rt]

In Str\split, if $limit is provided, the last element of the return is special, in that it contains the entire remainder of the string. This could be better structured as a tuple of (vec<string> $parts, string $remainder).

Regex\split suffers from a similar issue.

Perhaps it might be best to make seprate functions for with-and-without limits?

list($parts, $_) = Str\split($haystack, $delim) feels verbose/confusing for the common case

Perhaps it might be best to make seprate[sic] functions for with-and-without limits?

list($parts, $_) = Str\split($haystack, $delim) feels verbose/confusing for the common case

... and expensive. creating a 2-element tuple where one element is almost always ignored feels wasteful.

if the caller is providing $limit, they could also $remainder = C\lastx($parts), splice it, or overwrite it via $parts[C\count($parts) - 1] = ''.

i suggest this old issue be closed until a push request is attached to it w/ the second function (Str\split_remainder?).
