Well, this is exactly what happens with closures, so one could argue that there
is precedent.
Not at all. The closure code does not *copy* the data to the heap. It is
allocated on the heap to start with.
I also find this pattern to be very useful. The LLVM support libraries even
package it up into a nice llvm::SmallVector<T, n> template that allocates space
for n elements inside the object, falling back to heap allocation only if that
threshold has been exceeded (a tunable small string optimization, if you want).
Nice!
