would be nice if the spec could state the maximum length of a symbol name before md5 compression is put to use.

This is not part of the D spec, but rather a hack in the Windows implementation of DMD to get around the shortcomings of the OMF format that it uses.  No other D compiler uses it.  If anywhere, it should be documented on the DMD page.

There isn't really a fixed length, as the compiler first tries to compress the identifier. If that fails to get it small enough, then it does the md5 hash. But it shouldn't be part of the spec, as it's an implementation issue.
