Re: Amicable numbers in Nim and a few questions

**petevine:** _It would be good for usability if the nim compiler offered 
automated profiled builds as well as pass the expanded CFLAGS via --passC 
automatically in release mode._

You can do this via a `<project>.nims` config file, e.g.:
    
    
    import strutils, sequtils
    
    let cflags = getenv("NIMCFLAGS").split(" ").filter(
      proc(x: string): bool = len(x) != 0)
    
    for cflag in cflags:
      switch("passC", cflag)
