If we're going to redo syntax, we might as well adopt a much less
ambiguous (and prettier!) function declaration syntax based on
mathematical notation (which is also adopted by some functional
languages):

	funcName : type1 arg1, type2 arg2, ... -> returnType

For example:

	pow : real base, real exponent -> real
	{
		// Variable declaration
		tmp1 : real;

		// Variable declaration with initializer
		result : real = dotDotDotMagic(base, exponent, tmp1);

		// Statement as usual
		return result;
	}
