This test program uses some of the Webkit types (in
src/3rdparty/webkit/JavaScriptCore/wtf in qt-copy):
#include <string>
#include <HashMap.h>
typedef WTF::HashMap<const char *,const char *> T;
void foo() {
T tbl;
T::HashTableType ttbl;
ttbl.add(std::make_pair(17,17));
tbl.set("foo","bar");
}
which fails to compile like so:
"t.cc", line 10: Information: Instantiating WTF::HashMap<const char*, const
char*, WTF::PtrHash<const char*>, WTF::HashTraits<const char*>,
WTF::HashTraits<const char*>>::set(const char*const&, const char*const&).

which I fail to understand. Any takers?
