Tikz seems to be broken under luatex.
As is, compiling something as simple as
\usemodule[tikz]
\starttext
Hello, world!
\stoptext
gives errors.

Hi!
arggh....
Discerning the driver is really a problem in ConTeXt, at least for a non-context-guru like myself.
As a quick fix, you will have to define the driver yourself by saying
\def\pgfsysdriver{pgfgsys-pdftex.def}
or whatever seems appropriate before tikz/pgf are loaded. That should shut up the (not-working) automatic driver detection.
Does some context-guru on the list happen to know what is the right, official way to find out which backend is used?
Best regardsm Till
This won't work with luatex (but it does compile without error messages) and I cannot (easily) figure out what the correct driver should be... Alan
