The "Exec" library is what you want to use. You can use it like this...
when ( local ret = Exec::run([$cmd="ls"]) )
The only thing to keep in mind is that the body of "when" statements are
only executed once the condition has completed. The body of the when
statement will be "registered" and execution will immediately continue
below the when statement so you many have to do something like have your
if statement you want to do *inside* the when statement's body.
