Seemingly Innocuous Template does not Compile

[fowlmouth]

type pnode* = ref object of tobject

template litNode (name, ty): stmt  =
  type name* = ref object of PNode
    val*: ty
litNode PIntNode, int

/tmp/aporia/a53.nim(7, 0) Info: instantiation from here
/tmp/aporia/a53.nim(6, 7) Error: illformed AST: val(*|*|*|*|*|*|*|*)

This was working fine a few commits ago, it should have immediate but it was working fine without it. (Adding immediate does not fix it.)

this also crashes Error: undeclared identifier: 'x', maybe related?

import json

template withKey* (J: PJsonNode; key: string; varname: expr; body:stmt): stmt {.immediate.}=
  if j.hasKey(key):
    let varname{.inject.}= j[key]
    block:
      body

var j = parsejson("{\"zzz\":1}")
withkey(j, "foo", x):
  echo(x)
