That said, I was very interested in CoffeeScript as part of my job is to write new whiz-bang features into applications that run on older browsers (such as the IE7 I visited you on today.)
Bear in mind, CoffeeScript especially appeals to people in my position. It just sucks I can't read it / play with it now.
Still, I've bookmarked it for later reading from home, so hopefully I won't forget.
Any idea how far away you are from putting out something one might consider 'stable'? I'm in the government, and it's effectively impossible to use 'beta' code here.
Fortunately, you don't have to take my word for it. Even if the CoffeeScript compiler were to disappear in a puff of smoke this afternoon -- you'd still be left with pretty-printed, quite-readable JavaScript. It's not like depending on a beta of a VM or interpreter.
Also, I can't read the first paragraph of text, as the toolbar is hovering over it.
