This leads to:
```
gdc lambda4.d
lambda4.d:28:25: error: template compose(E)(E a) has no value
int function(int) t = compose!(f,g,g,f,g,g,f,g,g,f);
```
Try using the address operator:
// Here
// ▼
int function(int) t = &compose!(f,g,g,f,g,g,f,g,g,f);
Hello,
thanks for the hint. But in my environment I am getting the same
error:
```
gdc lambda4.d
lambda4.d:29:26: error: compose(E)(E a) is not an lvalue
int function(int) t = &compose!(f,g,g,f,g,g,f,g,g,f);
```
However this works:
```d
int delegate (int) td = (x) => compose!(f,g,g,f,g,g,f,g,g,f)(x);
```
