until

Control-struct: until

file: job.t
package: muf
status: alpha

This construct provides a loop with a termination test at any point:

Stack: 1 2 3 4 5 6 7 8
do{ 5 = until }
Stack: 1 2 3 4

On each iteration, the until operator pops one value off the stack: if that value is non-nil, control is transferred to the first statement following the loop, otherwise execution continues normally past the until.
