Re: How do I make macros that build up and use data structures?

[iffycan]

I think I've found a solution that will work for me (still working through all 
the details):

I define `mkParser` and `flag` as `{.compileTime.}` procs. Then when I want to 
make a command line parser, in my application code, I define and use a macro 
like this:
    
    
    macro makeParser(): untyped =
      return mkParser("some name"):
        flag("-a")
        flag("-b")
    var p = makeParser()
    
    
    Run

I think it would be cool if Nim supported doing stuff like this without the 
wrapping macro syntax, but it's way cool that Nim supports this at all!
