Ok - not sure why I was not able to reproduce before: I put a
breakpoint on line 179 of restricted, and sure enough code, when it
had no ending newline, would cause an error.
This seems like it is a bug with the builtin, compile() ...
For now, this should be harmless, and ensure this doesn't happen:
in gluon/restricted.py, change line 179 as follows:
< before:
ccode = compile(code.replace('\r\n', '\n'), layer, 'exec')
> after:
ccode = compile(code.replace('\r\n', '\n')+'\n', layer,
'exec')
