No, that's not the reason. ScopedValue is implemented using Callables because
it is the only way to make the structure robust. While this has implications for
preventing memory leaks, robustness implies much more than that.

Among other things, it means that we can use scoped values to carry handles
which access capabilities, e.g. foreign memory access.

A better question to answer, IMO, is how to add enough syntactic sugar around
Lambda calls to handle Exceptions nicely. The Lambda itself doesn't have to be
visible to the programmer.
