How can I deal with `emit`? When I use `emit` in global scope, it generates
`emit` statement before normal Nim code.
import parseutils
template procName*: string =
when declared(NimMainModule):
echo "sdf"
when not declaredInScope(internalCProcName):
var internalCProcName {.exportc:"__the_name_should_not_be_used",
inject.}: cstring
{.emit: "__the_name_should_not_be_used = __func__;".}
var realProcNameButShouldnotBeUsed {.inject.}: string
discard parseUntil($internalCProcName, realProcNameButShouldnotBeUsed,
"__")
realProcNameButShouldnotBeUsed
echo procname()
Run
It got crashed.

It generates C code like:
__the_name_should_not_be_used = __func__;

I need something like this:
/* section: NIM_merge_VARS */
N_LIB_PRIVATE NCSTRING __the_name_should_not_be_used;
N_LIB_PRIVATE NimStringDesc*
realProcNameButShouldnotBeUsed__Ipp9c7O8sXEIShSL2Z09bqPw;
......................................................................................
__the_name_should_not_be_used = __func__;

Can I achieve that? Any suggestion? Thanks in advance.
