For example, the program 

-------------------------------------------
module y;
template TTTTTTTTTT(float v) {
    void TTTTTTTTTT() {
    }
}
void main() {
    TTTTTTTTTT!1.0f();
    TTTTTTTTTT!(float.nan)();
    TTTTTTTTTT!(float.infinity)();
}
-------------------------------------------

generates the symbols

_D1y22__T10TTTTTTTTTTVfeINFZ10TTTTTTTTTTFZv
_D1y22__T10TTTTTTTTTTVfeNANZ10TTTTTTTTTTFZv
_D1y23__T10TTTTTTTTTTVfe8PN3Z10TTTTTTTTTTFZv

which the demangler can only recognize 1 out of 3:

void y.__T10TTTTTTTTTTVfeINFZ.TTTTTTTTTT()    // fail
void y.__T10TTTTTTTTTTVfeNANZ.TTTTTTTTTT()    // fail
void y.TTTTTTTTTT!(1).TTTTTTTTTT()            // ok
