Is GC called every iteration of this loop?
No, it will once on scope entry; where the deepest-referenced
variable that is actually captured is defined. The compiler
allocates heap space instead of stack space for the locals,
then runs the function normally using that space.
Excuse me, I can't get what does it mean "deepest-referenced".
What the deep you mean? The deep of a closure or deep of the
function where the variable is defined. Can you give an example
code?
It will only alloc once. You can prove this with a debugger
btw, set a breakpoint on `_d_allocmemory`.
Is this function called every time when allocation happens in a
heap?
Thank you. Sorry if my English is not clear.
