[ke]

Can be worked around by skipping (not autocompleting) the compilation step.

[ke]

Deprioritized, can work around it by skipping the compilation step.

[ke]

Possibly related to #133? Does it also happen with new TRALE revisions (308)?

[ke]

The reason is that a unify step appears outside of any variable-scoping step (rule, comp_clause, fun_clause, cons, lex, lr), resulting in an attempt to peek at the empty varscopestack. Below's a trace.

This *might* have to do with the unify step appearing as an unblocked goal. This would point to a deeper issue, it would indicate that we are not maintaining the varscopestack properly for delayed goals (I fear this is the case). But the reason may also be simpler - we might just not have a complete list of variable-scope-introducing step types yet.

Further investigation needed.
