Add strict operator #99

Open MattWindsor91 opened 2 years ago

MattWindsor91 commented 2 years ago

We have the parallel, alt, and loop operators already, but at least one example in the testbed requires the strict operator.

Semantics of the strict operator, given a cursory glance of COMPASS D22.4, looks like we introduce a channel strict.x.y for every strict step x and nested element y, and use them to synchronise after every y. So the pseudo-RoboCert

strict:
    always:
        op foo from A to W
    always:
        op bar from B to W
    always:
        op baz from C to W

becomes something like

A = fooCall -> strict.0.0 -> strict.0.1 -> strict.0.2
B = strict.0.0 -> barCall -> strict.0.1 -> strict.0.2
C = strict.0.0 -> strict.0.1 -> bazCall -> strict.0.2

Moving to milestone 1 as I think this might be mockable using UntilFragment.
