Passing a defined proc to dot operator macro results in assertion error

[vijaymarupudi]

Example

# test.nim
import jsffi

proc log() {.varargs, importc: "console.log", cdecl.}

let d3* {.importc.}: JsObject

let svg = d3
  .call(log)

nim js test

Another example

import jsffi

let d3* {.importc.}: JsObject

proc l() {.varargs, importc: "console.log".}

d3.call(l)

Current Output

Error: unhandled exception: sigmatch.nim(1021, 9) `aOrig != nil`  [AssertionDefec
t]

Expected Output

For it to compile. Or error due to competing values of log

Possible Solution

Unsure

the example code will leading to unknown behaviour, js call takes function, context, ...args,
your example d3 is object which is not callable, and if there is call proc in nim d3 will be first param, this will cause log into context position which will also leading to unexpected behaviour, issue here should separate to serveral issues.
