cgi.q should be ok (at least the version included with the Q core 
package is), I checked that.

Thanks to the migration path suggested by John, fixing the 1-tuples is a 
trivial business. Simply install Q 6.1 first, feed your scripts to it, 
and fix all places where the compiler warns you about the deprecated 
1-tuple syntax (adding a comma at the end of the tuple is enough). Your 
scripts will then run with Q 6.2 just fine.

BTW, despite all testing one error has crept in: The except.q script in 
the examples of the core package won't compile. The fix is trivial, and 
an updated version of the script is already in cvs.

You couldn't. ;-) Even the (in) operator, which is used in the standard 
library to construct list and stream comprehensions, had to be 
hard-coded into the parser. I'm glad that this is fixed now.

Ok, the two remaining big issues now are unicode and 64 bit support. I 
plan to do this for Q 6.3. Back to coding...

Cheers,
Albert
