Another oddity i did not like at first but must admit is growing on me
vector.reverse --> returns a new reversed vector
vector.reverse! --> modifies the instance vector in-place
Of course in python you would do...
vector.reverse --> in-place
vector.reversed --> in-place
The above example works pretty good, but this doesn't always "sound"
good. Take for example this...
point3d.offset --> return a new pt
point3d.offseted --> What did you say!?!?!
Now try Ruby's way
a symbol works better for these things
