This does work:

Is there something with the types of {{v}} and {{0}} that cause this?
! Orc team response
|| Analysis
| __Repeatable:__ | Yes
| __Root Cause:__ | OrcScala bug. {{random(1)}} returns a {{java.lang.Integer}} which, when its {{equals}} is called with the {{scala.math.~BigInt}} literal {{0}}, fails to compare as equal. ~OrcJava had work-arounds in its {{orc.runtime.sites.core.Equal}} site for this.
| __Proposed Fix:__ | Update {{orc.lib.builtin.Eq}} to replace use of {{equals}} with Scala's {{==}}, which handles boxing correctly.

! Reporter's comments:
Constraint generation seems to behave strangely in the presence of nested constructors. The underlying constraint {{{List[Bot] <: List[List[Top]]}}} should succeed trivially, but instead it fails. This is the simplest example I have found which demonstrates the problem. In fact, the expression should have the even more precise type {{{List[List[Bot]]}}}, but I've currently left it as {{{Top}}} for simplicity.
