Something like table.slice(src: {...}, from: number, to: number) -> {...}

Or maybe table.slice(src: {...}, start: number, amount: number?) -> {...} where amount is optional and works like string.sub(...)

As I'm the one who submitted the PR to deprecate ll.List2List, I feel a bit responsible and have kept this feedback on my mind. I've been dogfooding in my own code whether I can replace

ll.List2List

in every instance. So far I can. Unlike all of the other list function deprecations in that PR, this one actually does have a direct substitution (two in fact:

unpack

and

table.move

). Here's what I've actually replaced it with, from most to least common:

changing strided lists to lists of dictionaries
string.gsub
(when used with
string.split
and
table.concat
)

Some other replacements that have been proposed, but I haven't yet used in my code:

using the optional 3rd and 4th parameters of
table.concat
using the optional 2nd and 3rd parameters of
unpack
/
table.unpack
(a direct substitution)
'table.move(..., 1, {})` (a direct substitution)

Notably, I have not yet used either of

ll.List2List

's nearly-direct substitutions. These are equivalent when a and b are positive. The direct substitutions are:

ll.List2List(list, a, b)
table.move(list, a, b, 1, {})
{unpack(list, a, b)}

I suspect having these direct substitutions helped make the case to deprecate

ll.List2List

alternately, we could revert the deprecation of ll.List2List

ll.List2List(list, a, b)

is exactly equivilant to

{unpack(list, a, b)}

except I usually don't even need the surrounding '{}', because I'd rather have the values inside the list as local variables

I vote for

table.slice(src: {...}, from: number, to: number?) -> {...}

, with

defaulting to

#src

SuzannaLinn Resident I agree, and for completeness, have from default to 1.
