Typed macro removes `std /` in imports

[HugoGranstrom]

When passing an import using the syntax:

import std / [jsonutils]
import karax / [kbase]

to a typed macro the first part of the import is removed resulting in this:

import jsonutils
import kbase

which gives an error like:

Error: cannot open file: jsonutils

Note: If you replace typed with untyped it works.

Example

import macros

macro identity(body: typed) = echo body.repr result = body

identity: import std/[jsonutils]

### Current Output

import jsonutils

C:\Users\hugog\code\nim\nimib\a.nim(7, 1) template/generic instantiation of identity from here C:\Users\hugog\code\nim\nimib\a.nim(8, 13) Error: cannot open file: jsonutils

### Expected Output

import std / [jsonutils]

### Possible Solution

* No idea sadly

### Additional Information
Have tried it on version 1.6.6, 1.6.0, 1.4.8, 1.4.0, and the latest devel. All give the same error.

weird, I just tried , if you change the module to other like jsonutils -> cstrutils , it will not error you.

It's because some modules in the stdlib requires the std / prefix while others don't. jsonutils is one which requires it while cstrutils doesn't. Try this code for example:

import jsonutils
# Error: cannot open file: jsonutils

While this one works:

import cstrutils
