Refer issue #3514

I separated the code present in function modifier with 2 (private) functions outside & just call those function(s) from inside the modifier.

Hello @abhi3700 and thank you for this PR.

I think we would want better naming. Maybe something like _nonReentrantBefore, _nonReentrantAfter ?

Did you measure the additional runtime cost?

In my repo,
the compile result with standard "ReentrancyGuard" is 9.72s
image

And the compile result with standard "ReentrancyGuard" is 9.29s
image

The compile time differs because of the machine running concurrent applications at this time.

So, it can be seen that the contract size is highly reduced by 0.308 KB
