You can call `alloca` as a default argument to a function. The
memory will be allocated on the caller's stack before calling
the function:

One way to do that in D is to use `alloca`, but that's an issue
because the memory it allocates has to be used in the same
function that calls the `alloca`. So you can't, e.g., use
`alloca` to alloc memory in a constructor, and

Yes, dcompute could mean
That is awesome to hear!
If the move towards ldc has the potential to half your run time, that is
quite a significant improvement for your customers.

Bastiaan reported that SARC had been testing their D codebase
(transpiled from Pascal---[see Bastiaan's DConf 2019
talk](https://youtu.be/HvunD0ZJqiA)). They'd found the
multithreaded performance worse than the Pascal version.
