Yeah .. users... erh...

.. but compiler writers are a different breed all together.

(well, they used to be anyway)

It used to be, that the golden rule of compiler writers was 
"performance is (almost) everything".

i.e.

- Compile time performance -> how long it takes to generate code.

- Runtime performance -> how fast that code runs.

(Almost) nothing else used to matter (to compiler writers)

Why almost? Cause in the end, you need accurate results more than 
you need speed.

I see the performance of (other) compilers these days, and I 
wonder.. what ever happened to that bread of compiler writers... 
from long ago...

Luckily, we still have one of them.
