* fix#10339 by checking for nkObjConstr
* revert check for nkObjConstr, return type from nkEmpty node
The correct type needed in `semObjConstr` to fix#10339 is indeed
available, but attached to an `nkEmpty` node. These were previously
discarded in `semTypeNode`, which is used to extract the type for the
object.
* simplify return of PType from `nkEmpty`
* also fixes#9866, add test case
* Fix result not being able to use in quote do
This fixes the annoying issue of not be able to use result inside a
quote do block. It works by a simple trick. The quote do mechanic is
based on dynamically creating a template and immediately calling it with
the arguments found within the quote do block. Since this is called in
the scope of the macro the result variable is shadowed. This trick works
by changing all occurences of result (which shouldn't cause any issues
as result isn't used for anything else for the same reason) to another
name and then passing in an IdentNode with result as a named parameter
with that name.
Note that currently this just replaces it with a fixed named variable
"res" which should be changed to a non-colliding, dynamically created
name.
* Fix hard coded parameter "res" to anonymous symbol
This fixes the hard coded parameter "res" to be an anonymous symbol
instead so it won't collide with other parts of the argument list.
* Add test case for result in quote do block
A simple test case based on GitHub issue #7323 on how you can't put
result in a quote do block. This test verifies that it actually works
correctly now.
* Add test for explicit capturing of result
* Rebased against devel
