Invocation: build a Lambda to activate the »Trap« and then to forward the invocation to the actual function, which should have been initialised by the delegate invoked.

Parameters

delegate

a functor object to forward invocation; the delegate must return a reference to the actual function implementation to invoke. Must be heap-allocated.

Returns

a lightweight lambda usable as trigger.
