Assertions

#include <fennec/lang/assert.h> 

This header contains macros for making assertions about code behaviour.

fennec defines the following assert implementations:

Syntax	Description
assert(expr, desc)	Make an assertion with expression expr and provide a description desc. Only halts in debug mode.
assertf(expr, desc)	Make an assertion with expression expr and provide a description desc. Always halts.
assertd(expr, desc)	Make an assertion, only in debug mode, with expression expr and provide a description desc. This should be used when the branching caused by assert would hinder performance in release mode.
