I know. The problem is that FUNCTOR: QList evaluates its contents
when it is parsed.

QList<T> will exist when the functor is called. In code with the
unimportant bits elided:
FUNCTOR: QList ( T -- ) ... ;FUNCTOR
SYNTAX: QLIST: scan QList ;
CLASS: QPoint ;
CLASS: QList<QPoint> ;
QLIST: QPoint
This code barfs at line one because it tries to create QList<T> when
FUNCTOR: QList is defined; instead, it should create a QList<QPoint> at
the last line.
It's frustrating me no end because I just can't see what I'm missing.
