 From what I can tell `alloca` is only available in the platform's 
C standard library (actually for Linux it appears be part of 
libgcc as `__builtin_alloca`; `alloca` is just and alias for it). 
  Of course I can use 3rd party libraries like C to do this, but 
it seems like something useful to have in the language for 
certain use case and optimizations.  Also, my immediate use case 
if for bare metal microcontroller programming where I'm 
intentionally avoid C and looking for a way to do this in 
idiomatic D.
