----------------
hekota wrote:
`setHandleFieldOnResource(PH::LocalVar_0, PH::LastStmt)` is assigning the value
of the last statement (=result of the builtin call) to the resource handle
field to the first local variable in the method. Then then it is returning the
local variable. I will add a comment to the
`addCreateFromBinding`/`addCreateFromImplicitBinding` methods explaining how
the body looks like.
