  Maybe. I barely have ever used alloca myself, but glancing over 
the VLA's it seems iffy. If there's just one it's easy to 
implement, however if there's several then the data would point 
to a slice on the stack. I can see how it works in my head, but 
with dynamic arrays, malloc & scope you can get a similar affect. 
Hmmm... Maybe a possible use for a template instead?
