0.3

Rattus code is now checked just after GHC's type checking phase (instead of after desugaring to Core). As a consequence, error messages for some corner cases are much improved and we don't need to use the -g2 compiler option anymore to get good error messages.

0.2

• the use of lazy data structures will now cause a warning (can be disabled by 'AllowLazyData' annotation); this check for lazy data is rather ad hoc and needs to be refined
• allow functions under ticks (but with limitations, see paper)
• strictness transformation is now similar to the 'Strict' language extension
• optimisations using custom rewrite rules

0.1.1.0

• allow mutual guarded recursion
• improve type error messages
