Defining functions in geekest mode

[totalgee]

Hi there, this is a great project! I like the "geekest" mode, where you have a few extra helpers and definitions like snoise2D() available, and don't need to write the main() definition. However, this means you can't create/use helper functions. Since the calling code just wraps the main() definition before and adds a closing brace afterwards, it is actually possible to define functions after, like this (which compiles fine under geekest 300 es):

vec2 uv = (FC.xy - 0.5*r) / r.y * 1.;
for (int i = 0; i < 8; ++i) {
  uv = abs(uv) / dot(uv, uv) - 0.7 + sin(t*0.75) * 0.2;
  uv += snoise3D(vec3(uv * 0.2, 0.01*t)) * 0.25;
}
o.xyz = (1. - vec3(pow(length(uv), 0.25))) * hsv(sin(uv.x*PI + t),1.,1.) * 2.;
} // end of main()

float test(float x) {
  return x * 2.;
// Note: no closing brace because it's provided by the wrapper!

However, you can't call test(), because it's not declared before main(). Besides #define macros, is there no "hack" to allow you to define and call functions in geekest mode? Otherwise, could the helper methods (and FC) be also exposed in geeker mode? Basically, what I'd like would be a "geekest" mode that allows you to write the main() definition. Maybe the code could check if it finds a void main() in the code, and if so, doesn't wrap it.

(I've made a PR with a possible solution for this.)
