 #### O1HEAP_ASSERT(x)
 
 The macro `O1HEAP_ASSERT(x)` can be defined to customize the assertion handling or to disable it.
-To disable assertion checks, the macro should expand into `(void)(x)`.
-If not specified, the macro expands into the standard assertion check macro `assert(x)` as defined in `<assert.h>`.

 #### O1HEAP_LIKELY(x)
 
 Some of the conditional branching statements are equipped with this annotation to hint the compiler that
 the generated code should be optimized for the case where the corresponding branch is taken.
 This is done to reduce the worst-case execution time.
 
-The macro should expand into a compiler-specific branch weighting intrinsic,
-or into the original expression `(x)` if no such hinting is desired.
+The macro should expand to a compiler-specific branch weighting intrinsic,
+or to the original expression `(x)` if no such hinting is desired.
 If not specified, the macro expands as follows:
 
-- For some well-known compilers the macro automatically expands into appropriate branch weighting intrinsics.
-  For example, for GCC, Clang, and ARM Compiler, it expands into `__builtin_expect((x), 1)`.
-- For other (unknown) compilers it expands into the original expression with no modifications: `(x)`.
