According to cppreference, assert will be used as a C++ attribute.
However, there already exist tons of projects heavily dependent on the macro assert, is there any bad effect?

Are they replacing it with anything or just removing useful functionality? – solarflare Sep 19 '18 at 02:35

2There is no problem, because the word `assert` won't be followed by a `(` so it won't invoke the function-style macro. – user253751 Sep 19 '18 at 02:35

1@solarflare Nothing is being removed. – Barry Sep 20 '18 at 01:32

No. The proposal p0542r5 which introduces C++20 contracts says:
Note that while
assert(expression)would expand as a function-like macro with the appropriate header,assert:is not a function-like invocation, so does not expand.

The new use of assert won't cause any problems, because it is not followed by a ( and therefore the function-style macro assert(blah) won't be invoked.
