Suggestion: Add error or warning if no @pool (or equivalent) when temporary allocator is used.

Observation: Common feedback I see on C3 code is that there are many memory leaks.
Goal: Promote the temporary allocator by making it a default choice in C3 0.7

Complimentary to that goal and observation may be detecting if there is a @pool(){} (or equivalent) in the context where the temporary allocator was used. This may then prompt people to the solution via an error or warning fix the memory leak issue, leading to a nice quality of life improvement.

Cool idea.

BTW, what if this @pool would initialize temp allocator engine internally too if it wasn't initialized before? Therefore, we might get rid of tmem() macro, in favor of tmem built-in (because all initialization mechanics will be in @pool call)

That would prevent giving a nice error on trying to use the temp allocator outside of a @pool

Note that 0.7.0 is already moving towards a temp-alloc-by-default use.
