Error using toSeq in map

[hbwales]

Using toSeq in map causes and internal error

Example

import strutils, sequtils
var data = "aaa aaa"
echo data.split(" ").map(toSeq)

Current Output

Error: internal error: D:\a\nightlies\nightlies\nim-1.4.2\compiler\seminst.nim(328, 18)
No stack traceback available
To create a stacktrace, rerun compilation with './koch temp c <file>', see https://nim-lang.github.io/Nim/intern.html#debugging-the-compiler for details

Expected Output

@[@['a', 'a', 'a'], @['a', 'a', 'a']]

Additional Information

$nim -v
Nim Compiler Version 1.4.2 [Windows: amd64]

#11992 would fix this (and the general case as well), until then you can use mapIt instead of map

when true:
  import strutils, sequtils
  var data = "aaa aaa"
  echo data.split(" ").mapIt(toSeq(it))

Doesn't crash and gives a proper error now (got template (x: untyped): untyped ...) which is reasonable to me
