As a sanity check for myself if you remember a while ago I posted about an idea
for “stack aliases” to override the memory allocation for classes. No one
really liked the idea and lots of potential safety concerns were raised (fair
criticisms).
By random chance today I came upon this feature of C# which basically does the
same thing I was suggesting, as a way to override the default functionality of
C# to allocate everything on the heap and garbage collect later. The reason
stated for the feature is because it’s an optimization over the default
heap-only allocation enforced for arrays.
So it looks like my idea wasn’t that crazy after all. ;) Granted C# needs this
feature more than FPC does because C# amazingly can’t allocate arrays on the
stack otherwise (now that’s crazy!) but never the less the inclusion of
“stackalloc” in C# gives the idea some credibility for FPC.

2 remarks:
1. It's only for arrays
2. It's for fixed-length arrays
So you can do this in FPC today.
Thirdly, you have objects which can be allocated on the stack, or advanced
records.
Plenty of choice for you.
Michael.
