New features

• The repeat statement now adds a variable _repeat_index to keep track of the current iteration number.
• Changed the @metadata system : arguments must be raw values.
• Added a @param(<var_name>, <type>) metadata tag. It guarantees a specific variable will exist on runtime. This allows more complex recursive spellc calls (i.e. allow for "scripting").

Bug fixes

• Some blocks did not apply their runtime inheritance.
• Fixed the stop scope backtrack.

Miscellaneous

• Added a bStat reporting.
• Cleaner way to add a function (no need to add the function name again).
