Doh, it turns out you're right, it is valid rpython, the problem was elsewhere. I was assuming the transform function was at fault because the error only happened when that was included in the build. It turns out correlation doesn't equal causation :-)<br>
<br>The actual bug was this:<br><br>[translation:ERROR] Exception': found an operation that always raises AttributeError: generated by a constant operation: getattr(<AliasModule 'py.test' for 'pytest'>, 'config')<br>
<br>Which I managed to fix by putting this lovely hack at the top of my script:<br><br><pre style="font-family:Consolas;font-size:13;color:black;background:white;"><span style="color:blue;">class</span> FixConfig<span style="color:teal;">:</span>
<span style="color:blue;">class</span> option<span style="color:teal;">:</span>
view <span style="color:teal;">=</span> False
py<span style="color:teal;">.</span>test<span style="color:teal;">.</span>config <span style="color:teal;">=</span> FixConfig <br></pre><br><br>Everything seems to be working now. Thanks to both Carl and Leonardo for the help!<br>

</div>You could take a look at the test test_translate_ast_visitor in<br>
rlib/parsing/test/test_translate.py. It does what you need to do by<br>
explicitly calling visit_[initial rule] on the AST visitor. I tried to<br>
replace that with a call to transform and it still worked. So I don't<br>
know what you are doing differently from that test.<br>
