I'm guessing

     size_t toHash() const @trusted pure nothrow
     {
         import core.internal.hash : hashOf;
         if (isSmall)
         {
             return this.small.hashOf;

         else
         {
             return this.large[].hashOf;
         }
     }

Why not just "return this.asSlice.hashOf;"?

Will

     this.large[].hashOf

do unneccessary GC-allocations? -vgc says nothing.

No.
