A new version is out. I will start work on the relationships between resources just after this one.

New features

• Errors now print a stack trace (only works with profiling builds)
• Nested classes
• generate() function
• defines with spurious top level statements now should work
• validate_* functions from puppetlabs/stdlib

Bugs fixed

• Metaparameters now include stages (not handled)
• Resolving non empty arrays as boolean returns true
• Duplicate parameters are now detected
