Hey there,
I'm wondering how I can use a template function within my mixin:

```
                ubyte[] value = x[33, 3a,3f, d4];
                foreach (type; TypeTuple!("int", "unsigned 
int", "byte"))
                {
                    mixin(`if (value.length == type.sizeof)
                            {
                                ubyte[type.sizeof] raw = 
value[0..$];
                                auto fValue = 
raw.littleEndianToNative!(type);
                                displayinfo(fValue);
                            }
                            break;
                        `);
                }
```


Error: template std.bitmanip.littleEndianToNative cannot deduce 
function from argument types !("int")(ubyte[8]), candidates are:
[..]\src\phobos\std\bitmanip.d(2560,3):

```
`raw.littleEndianToNative!` ~ type ~ `;`
```

Did you also put the ` ~ type ~ ` on the 2 other cases where you 
use the variable type?

     mixin(`if (value.length == ` ~ type ~ `.sizeof)
               {
                  ubyte[` ~ type ~ `.sizeof] raw = value[0..$];
                  auto fValue = raw.littleEndianToNative!(` ~ 
type ~ `);
                  displayinfo(fValue);
                }
                 break;
            `);
