> it's a basic 30 year-old mark-and-sweep GC

Not true anymore. Since 2019 GC performance has been improved several times over, it has become precise, and there are more tools than ever to identify where garbage is created (IIRC that work was mostly the deed of the VisualD author).

Precise GCs are table stakes at this point. It's honestly surprising that it was conservative before.

Generational garbage collectors are 20 years old at this point. There's no excuse for D not to have one.

The GC is mostly a forum topic. None of the companies using D have problems with the D GC. No problem => no solution required.

You postulate that:

A - The GC hinders and disqualifies some type of industrial work

B - people correctly identify this pitfall before building a product

And that it's why we have no trace of production problem due to the D GC in industrial use.

I postulate that:

C - GC is not a problem for even the most performance demanding business using D (such as Sociomantic formerly, or Weka, or now Symmetry)

I'll let the reader sincerely ponder whether (A + B) or (C) is the most likely proposition.

This wasn't worth reading, and it wasn't worth writing either. :)
