`CATCH_CONFIG_FAST_COMPILE` has to be either defined, or not defined, in all translation units that are linked into single test binary, or the behaviour of setting `-b` flag and throwing unexpected exceptions will be unpredictable.
## `CATCH_CONFIG_DISABLE_MATCHERS`
When `CATCH_CONFIG_DISABLE_MATCHERS` is defined, all mentions of Catch's Matchers are ifdef-ed away from the translation unit. Doing so will speed up compilation of that TU.
_Note: If you define `CATCH_CONFIG_DISABLE_MATCHERS` in the same file as Catch's main is implemented, your test executable will fail to link if you use Matchers anywhere._
