List Cast
<lsl> //This function typecasts a list of strings, into the types they appear to be. //Extremely useful for feeding user data into llSetPrimitiveParams //It takes a list as an input, and returns that list, with all elements correctly typecast, as output //Written by Fractured Crystal, 27 Jan 2010, Commissioned by WarKirby Magojiro, this function is Public Domain list list_cast(list in) {

} </lsl>
Caveats
- Any strings fed into this function (which are meant to stay strings) cannot contain pointed brackets (<>) They will be cast as vectors or rotations, if they do.
