cannot attach a custom pragma to templates

[timotheecour]

cannot attach a custom pragma to templates

Example

template bar(a, body: untyped) {.dirty, used.} = discard
proc fun1() {.bar: 1.} = discard # ok
template fun2() {.bar: 1.} = discard # error: Error: cannot attach a custom pragma to 'fun2'

when false: # ditto with these
  template bar2(body: untyped) {.dirty, used.} = discard
  template bar3(body: untyped) = discard
  template fun2() {.bar2.} = discard
  template fun3() {.bar3.} = discard

Current Output

Error: cannot attach a custom pragma to 'fun2'

Expected Output

works

Possible Solution

• maybe do something similar to fix: var a{.foo.} = expr inside templates (refs #15920) (except when foo is overloaded) nim-lang/Nim#13869

Additional Information

• affects since in stdlib
• related but different from fix: var a{.foo.} = expr inside templates (refs #15920) (except when foo is overloaded) nim-lang/Nim#13869
• devel 31ba275
• template/macro pragmas don't work in templates (eg: byaddr, since etc) · Issue #15920 · nim-lang/Nim
• EDIT: now reported as cannot add custom pragma to templates nim-lang/Nim#18212
