[#FOLLY_SETTING]
= FOLLY_SETTING
:mrdocs:

Accesses a defined setting. Rationale for the macro: 1) Searchability, all settings access is done via FOLLY_SETTING(...) 2) Prevents omitting trailing () by accident, which could lead to bugs like `auto value = *FOLLY_SETTING_project_name;`, which compiles but dereferences the function pointer instead of the setting itself.
