Could you update the CI as well?

[stonemaster]

Sure, I am happy to check what's going on with the CI!

What is your opinion on the compiler versions used: should the old versions be replaced by recent LDC/DMD versions? At a first glance there are some random looking build errors but I don't know whether they are related to old compiler versions ..

[aminya]

Yes, I am fine dropping support for old compilers as long as we bump the major version

[aminya]

Sub flags are deprecated for dmd, they should be removed from the dub file

Thanks for the last commits. It seems that two build configurations failed because of "out of memory" :-|

Locally the lint command runs fine for me but outputs the following strange error:

...d-tree-sitter/script/lib/meson.d(0:0)[warn]: Variable  is never modified and could have been declared const or immutable.
