The un-demanglable symbols seem to be really complicated template instantiations, like randomShuffle!(chain!(... . IIRC there's some fundamental limitation where once a symbol gets huge DMD relies on hashing, so the mangling no longer has an inverse. Is this true, or is it worth spending some time trying to create a decent test case?<br>

Remove std.demangle and continue maintaining core.demangle.<br><font color="#888888">

I wasn't sure whether to fix std.demangle now that core.demangle works, or to replace/deprecate it. At the time I just needed something in druntime and I didn't like how std.demangle did everything via string ops. What do you all think?<br>

I've noticed that Sean has recently added the core.demangle module to<br>
druntime. Does this mean we can deprecate std.demangle? I've never<br>
used it myself, but I seem to remember people saying on the NG that it<br>
is pretty outdated.<br>
