That's the programmers' disease of never doing research, just start 
hacking, and reinvent the wheel on the fly. It's depressingly common.

The only ambiguity would be as someone said 4/2*2.

Btw, APL is consistent in right-to-left evaluation, so 4/2*2 is 1. 
I'm not sure if -2+2 would be -4 in APL. It's been too long.
