@erichkeane stepping through the test i added for a lambda returned from a
function, `NakedFn->getReferencedDeclOfCallee()` returns `nullptr` in the case
of a lambda returned from a function. i believe this is because `NakedFn` is an
rvalue, so there is no referenced decl to get.
using `cast_if_present`/`dyn_cast_if_present` seems to cover that case.
@zyn0217 yes, you are correct that `NakedFn` is a `DeclRefExpr` referring to
the `VarDecl` of the declaration. `dyn_cast_if_present` indeed works, though i
wonder--if `NakedFn->getReferencedDeclOfCallee()` returns `nullptr` in the case
of a lambda returned from a function, could we get away with just
`cast_if_present`?
