To extend on this, a later article talks about how the system is written on an "in-house language" ( http://www.joelonsoftware.com/items/2006/09/01.html ) called wasabi.

> FogBugz is written in Wasabi, a very advanced, functional-programming dialect of Basic with closures and lambdas and Rails-like active records that can be compiled down to VBScript, JavaScript, PHP4 or PHP5. Wasabi is a private, in-house language written by one of our best developers that is optimized specifically for developing FogBugz; the Wasabi compiler itself is written in C#.

So to avoid starting from scratch they introduced a new language/compiler? Hrm... I question the scalability of this solution, what if every company decided to do this instead of biting the bullet and doing a rewrite?

Advanced, functional programming and basic...
