[Q] Is there a quick way to tell whether build-fzf-tab-module has already been run?

[cohml]

When I execute build-fzf-tab-module, it takes a long time to run. Like a full minute or more!

Unfortunately - and without going into lots of needless detail that's specific to me - my dotfiles end up executing build-fzf-tab-module somewhat frequently.

So what I'd love is an easy way to deduce whether or not build-fzf-tab-module has already been executed, so that I can skip it if it's not necessary.

Is this possible to do?
