// FIXME: We want a type declared *here* for HeapString, but it gives a compiler warning:
//  error: type 'GCString' cannot conform to protocol 'HeapAllocatable' because it has requirements that cannot be satisfied
//  Even using the same exact code from LibGC/Heap+Swift.swift
//  This is likely because one of the required types for HeapAllocatable is not fully imported from C++ and thus can't
//  be re-exported by the GC module.
