Compilation Errors in DMD2.104.0 onward

[vnayar]

Starting with dmd-2.104.0, and at least in dmd-2.105.0, but not dmd-2.103.1, fluent-asserts no longer compiles. The problem appears to originate from using the concatenate operator ~ on types string and const(dstring), expecting an implicit conversion. The changelog does not appear to document such a change: https://dlang.org/changelog/2.104.0.html
