It would useful to not be lost in the world...
Eye located in the middle of forward side of turtle.
Usage:
light, r, name, id, meta = turtle.look(a,
where: a,b - a way to determine the scanline from the turtle eye, vertical and horizontal angles or tangenses;
light - light level of first block found;
r - if light level > 0 then r is a range to block found;
name, id, meta - if light level is high enough then turtle can see correct block info.
turtle.detect() can be upgraded too to
found, name, id, meta = turtle.detect()
where name, id, meta provided only if block found.
and of course slots contents needs to be known.
If you so much against giving out id and meta, at least allow us know the names.
