What about 
&& || ! case do done elif else esac fi for function if in then until 
while { } [[ ]]
in scripting engine. I think that time is completely useless. What do 
you think about select?

I think
jmp
je/jne
invert (not for last return)
exec
regexp (check if string matches regexp)
push
pop
getelem (get element from list)

should be enough
External commands would be eval and [[
functions can be stored directly by parser

I think just comparing (after \ one character is not compared) might be 
enough.
; newline ;; && || ! case do done elif else esac fi for function if in 
then until while { } [[ ]]
