Add support for simple lambda expressions in reverse mode

gojakuch commented 3 months ago

This commit provides support for primitive lambda expressions with no captures in reverse mode in the same way they are currently supported in the forward mode (#937). That is, the lambda expressions are not visited yet. Instead, the lambda functions are treated as a special case of functors.

Fixes: #789
