I'm getting the following exception (pasting the interesting bit here)
with r6591
File "/home/sylvain/dev/repos/jython/dist/Lib/compiler/transformer.py",
line 53, in parse
return Transformer().parsesuite(buf)
File
"/home/sylvain/dev/repos/jython/dist/Lib/compiler/transformer.py", line
130, in parsesuite
return self.transform(parser.suite(text))
NameError: global name 'parser' is not defined

Hi Lawouach, we don't fully support the compiler module and never will.
Though I'm curious, what library are you using that needs it? What's it
calling the compiler module?
From my explanation in issue #1161, about the compiler module:
Jython doesn't fully support it and never will, because a) it generates
.pyc bytecode that we don't use b) it heavily relies on the parser
module which we will never support either c) is pending deprecation and
was removed in Python 3
The parser module provides the low level innards of CPython's parser
(which is really nothing like ours), and the way to deal with AST going
forward is via the _ast module, which we support and was originally
added in CPython 2.5. We also support the ast (no underscore) module, as
well as the ability to pass modified/generated AST to the compile
function, which were both added in CPython 2.6
So migrating away from the compiler module will benefit libraries on
Jython 2.5 as well as Python 3 going forward

Hi Philip,
This comes from CherryPy using a module that evaluates config values
into Python values.
http://www.cherrypy.org/browser/trunk/cherrypy/lib/reprconf.py#L194
That being said, the workaround I'm using for now, is that when running
into an exception at that point, I'm doing a:
value = eval(value)
Which seems to work as far as I can tell so it's not blocking me per se.
I guess Jython should at least issue a warning statement about not
supporting the parser.

Note however that the eval() trick doesn't workk all the time as it
cannot reproduce some aspects of the unrepr() function.
