brainfuck++

I've an idea how about a programming language that's essentially brainfuck but with extra higher level commands.

for example a lot of time in brainfuck you write [->+>+<<] for n00 --> 0nn maybe you could be able to define keywords etc..

>>16
can we please discuss this brainfuckles committee

the following code:

[->+>+<<]

takes cells n,x,y to 0,x+n,y+n

how should this expressed?
