[julia-users] Iteratively building calls.

[Brandon Taylor]

Hi, I'm trying to come up with a reasonable syntax for iteratively building 
function calls. Here is the best I've got so far.

using Lazy
using DataFrames

type Call!
  e::Expr
end

function Call!(c::Call, e::Expr)
  c.e.args = [c.e.args, e.args[2:end]]
  c
end

@_ begin
  Call(:( DataFrame() ))
  Call!(_, :(e( a = 1, b = 2 )))
  Call!(_, :(e( c = 2, e = 3)))
  Call!(_, :(e( f = 2, g = 3)))
  eval(_.e)
end

I'm looking for suggestions for cleaner syntax.
