Nimony (Nim 3.0) Design Principles

>>andsoi+(OP)
The biggest thing I still don’t like about Nim is its imports:

    import std/errorcodes

    proc p(x: int) {.raises.} =
      if x < 0:
        raise ErrorCode.RangeError
      use x

I can’t stand that there’s no direct connection between the thing you import and the names that wind up in your namespace.

It needs to be this way so that UFCS works properly. Imagine if instead of "a,b".split(','), you had to write "a,b".(strutils.split)(',').

>>xigoi+MHb
ok I do not understand.

What is preventing this import std/errorcodes

from allowing me to use: raise errorcodes.RangeError instead of what Nim has?

or even why not even "import std/ErrorCodes" and having the plural in ErrorCodes.RangeError I wouldn't mind

Nothing, and it fact this works. To move to an example which actually compiles:

    import math
    
    echo fcNormal
    echo FloatClass.fcNormal
    echo math.fcNormal
    echo math.FloatClass.fcNormal

All of these ways of identifying the `fcNormal` enum value works, with varying levels of specificity.

If instead you do `from math import nil` only the latter two work.
