Looks cool but what's one toy problem that it can solve more efficiently than others?

Here is an example of it summing a huge set of numbers 100x faster than in C.

Note that it's not 100x faster than C, but than bend running on one CPU thread.

Running the equivalent C code takes ~2.3 seconds on my machine. Same order of magnitude as bend on the beefy GPU.

This is unproven (and not a toy problem), but I imagine it's going to do pretty well at compilers. The amount of time I'm waiting at work, hypnotizing the tsc process that sits at 100% CPU, wishing it was parallel...
