Question/Request For run.dlang.io

[bauss]

Not sure who to contact about https://run.dlang.io/ or anything 
so here goes.

Is it possible to have caching an optional thing?

When you're running snippets that has anything to do with time 
then you need to change the code every time to get proper results 
and it's tedious.

I thought there was a bug in my code, but it was just because the 
output was cached.
