json module cannot be imported in nimscript

[geekrelief]

https://nim-lang.github.io/Nim/nims.html says the json should be available to nimscript.

With --mm:orc enabled.

Example

test.nims:

import std / json

Run with: nim e test.nims

Current Output

C:\Nim\lib\pure\json.nim(465, 24) template/generic instantiation of `==` from here
C:\Nim\lib\system\comparisons.nim(298, 18) template/generic instantiation of `seqToPtr` from here
C:\Nim\lib\system\comparisons.nim(294, 25) Error: undeclared identifier: 'NimSeqV2'

Expected Output

No error.

Possible Solution

https://github.com/nim-lang/Nim/blob/7d0285853f4327a0a4f683e13971dc3429aad1f3/lib/system.nim#L1799-L1801 This prevents seqs_v2 from being included for nimscript.

Your min reproduction does not error so I can only assume you're attempting to compile the nimvm with orc or arc.

[geekrelief]

Yes, this is with orc.

--mm:orc
import std/json

fixed by https://github.com/nim-lang/Nim/pull/21379 since now it parses the whole module.
