Re: number parsing question

[HyperHacker <hyperhacker@...>]

I had the same thought just yesterday. It's nice in C to be able to
define coordinates like this for example:
//X, Y, Z
{+1.0,  0.0, -1.0},
{-1.0,  0.0, +1.0},
{+1.0,  0.0, -1.0}
However, there's not really much advantage versus leading positive
numbers with a space. Lua is meant to be simple and efficient, which
means generally not having unnecessary syntax such as this. I wouldn't
mind it being implemented, but I'd probably never use it.
