AST macros cannot change the syntax or introduce new syntax. C preprocessor macros and AST macros are not the same. I'm starting to regret that I called it "macros".
If it is powerful enough to do async/await but look like normal D syntax, then is going to suffer from these faults.
(A lot of the C++ macro abuse looks like normal syntax to the user, but it behaves in a way that the casual user would find completely unexpected. In the same vein, macro assembler abuse of macros did not introduce new syntax - the syntax for the macros was straightforward. It was what those macros *did* that made them incomprehensible.)
