A bug? Unbound Unbound in 1.3-alpha2 when a symbol is not set
Hi, Is it intended in 1.3-alpha2? I think the error message in 1.2 is way better (although not as user friendly as I wish to). Shall I report it? Where?

Re: A bug? Unbound Unbound in 1.3-alpha2 when a symbol is not set
Rich at the Conj explained that he wanted to remove a bunch of verifications each time a value was referenced to gain some speed. The basis was of his reasoning was that an unbound value is an exception more than a common thing and all these verifications at run time were really slowing things significantly for all applications. I recalls that he mentioned he needed to create the unbound value to achieve these optimizations. Luc P. Ken Wesson kwess...@gmail.com wrote ..

Luc is right. As to explain the behavior, see below: 2010/11/4 Jacek Laskowski ja...@laskowski.net.pl: Hi, Is it intended in 1.3-alpha2?
