🚀 go-pugleaf

I know that finding functions before builtins is probably more flexible,
but sh (on SunOS 3.5) (and ksh) find the builtin first.

Also, here are some things that would be nice to have.
I know it is easy to talk about additions, but some of them shouldn't
be too hard.

1. noclobber ( >| or >! would override)
2. variable PPID  (parent process id) - shouldn't be too hard
3. variable RANDOM (initialize the seed when assigning to it)
   shouldn't be too hard
4. logout if idle time too long - shouldn't be too hard
5. [^characters] in file name generation (doesn't match characters)
6. arithmetic (like ksh)
7. ulimit Hard or Soft (Soft if you want to have a limit temporarily)
   shouldn't be too hard
8. when reporting errors when sourcing (.), line numbers would be nice

Hope this helps.
