In a world where MetaObject Protocol hacks like methodMissing provide quick ways to create DSLs, Groovy's BuilderSupport class is a less known but a very powerful tool that makes this process easier and provides for some structure around such implementations. While prone to tree structures, a little tuning can create terse yet flexible vocabularies. Another approach to DSL's in Groovy involves a combination of Categories and Groovy's pseudo operator overloading. This approach may well provide much more fluent DSLs and a better organization of code. The session could (very well should) demonstrate several examples of such DSLs of varying complexity; but not before having demonstrated the plethora of builders already available in the Groovy ecosystem.
