void funOneArg()() {}
void func_pure_nothrow() pure nothrow {}

void foo()
{
    // commenting the next line in/out will change the mangling of *f2
    // enum f1 = &curry!funOneArg;
    enum f2 = &func_pure_nothrow;
    pragma(msg, typeof(*f2));
    pragma(msg, typeof(*f2).mangleof);
}

auto curry(alias fun, Args...)(Args args)
{
    return fun(args);
}

Roughly the issue is that the deco member for TypeFunction isn't updated
when purityLevel is deduced lazily.
In detail:
TypePointer for f1 and f2 are merged as their types are already equal when
evaluating the AddrExp.
Now both TypePointer alias the same TypeFunction but that was created from a
function without 'pure nothrow'. That's why the deco buffer does still contain
unattributed function.

There is also the side issue that f2's TypeFunction suddenly has an empty tuple parameter.
