I am seeing an "recursive expansion" error generated by ldc2 on some D code. Do you know how to extend the max number of recursive calls, as with the -ftemplate-depth= switch of GCC?

Bye and thank you,

There is no switch - the limit is hardcoded in the frontend source.
Does the source compile with dmd?

The program gives the same error message with dmd. Can't you replace this front-end hard-coded value with a value that optionally can be specified with a compiler switch (despite the risk of compiler crash)?

Yes, I can do this. I try to create a DMD pull request for it.
