Test case:

------------------------------
int f6356()(int a) {
    return a*a;
}
alias f6356!() g6356;     // comment this out to eliminate the errors
pure nothrow  safe int i6356() {
    return f6356(1);
}
------------------------------
x.d(6): Error: pure function 'i6356' cannot call impure function 'f6356'
x.d(6): Error: safe function 'i6356' cannot call system function 'f6356'
x.d(6): Error: f6356 is not nothrow
x.d(5): Error: function x.i6356 'i6356' is nothrow yet may throw

Raising severity because unaryFun and binaryFun are used in template
constraints or return types. This bug makes std.algorithm.equal not able to be
pure/nothrow/ safe, for example.

2nd test case:
-----------------------------
bool f6356b()() {
    return true;
}
void g6356b()() if (is(typeof(f6356b()))) {
    f6356b();
}
void h6356b() pure nothrow  safe {
    //f6356b();    // <-- uncomment to make it compile.
    g6356b();
}
-----------------------------
x.d(9): Error: pure function 'h6356b' cannot call impure function 'g6356b'
x.d(9): Error: safe function 'h6356b' cannot call system function 'g6356b'
x.d(9): Error: g6356b is not nothrow
x.d(7): Error: function x.h6356b 'h6356b' is nothrow yet may throw
-----------------------------
