Is there a compiler for Bourne shell or any other shell?  If not, is
anybody working on this?

Such a beast should draw frequent yet simple commands such as test,
cat, fgrep etc. into the C code (presumably) generated.  If there are
no traps, the last command should just be exec-ed w/o forking while
the others should have a hard wired fork/exec/wait.  When variable
substitutions are necessary they should have strcat or other calls in
place, and internal (i.e. assigned and not exported) variables should
just be char *.

Of course, if it's called upon to compile something like eval $1 `$2`
I suppose things get pretty hopeless.
