proc?

Hi All,

I use "run" a lot.

https://docs.raku.org/routine/run

It looks to me like "proc" is an OOP construction.

Where do I find its declaration so I can figure out
what all its members are?  (The above link does not
define it or I am blind.)

So far I know:
   $proc.exitcode
   $proc.err.slurp(:close)
   $proc.out.slurp(:close)

Yours in confusion,
-T
