Dug a bit more into it... It's getting interpreted as an attempt to
hyper-whatever a .new call (so like **.new), and the QAST gets added a call to
&HYPERWHATEVER, which returns the sub you see in the output.
No idea if there's any easy way to make it DTRT, so I'm going to leave this for
someone else...
