It seems like if we have a stack of static memory we should we able to use that instead of GetMem if we want to (like is possible for all other types). GetMem just find a memory address from RAM so why can’t there be a function that finds a memory address from the stack? In my mind I’m seeing this as a transparent implementation detail that the class handles for you inside the class method which allocates the classes internal pointer. Something in me says that we have this memory mapped at compile time so we should be able to access it.

'make it competitive with new entries in the market' is not a goal of the
free pascal team.
This is a hobby project for most devs. Monetary gain is not a goal.
Probably sounds like an anachronism in this day and age, but there you are...
