Oh? Yeah, you know: I write such a lot of code that
it's hard to remember the details even of my own programs ;)

Ah, correct. I've programmed it not defensive enough.  I've at the weekend
started to import ePerl into CVS and merge in the first bugfixes and cleanups.
I'll add this one, too. I hope I can provide you with an ePerl 2.3.0 for WML
1.7.0 the next weeks, Denis. 

BTW, is there already a proposed release date for WML 1.7.0?
I think at least to propose a date would be reasonable, even
when you don't treat it as a final deadline...
