What problem does Pyro solve?
It solves the problem that I wanted to build a programming language.
Why is it called Pyro?
I built the first prototype version in Python and it burned through CPU cycles. I think that qualifies as blazingly fast for marketing purposes.
Is Pyro fast?
No. Right now, Pyro is approximately as fast as Python, which is generally considered to be a slow language.
Pyro is designed to be highly optimizable so, in theory, future versions could run at least an order of magnitude faster, but for now this is a theoretical possibility.
