<pre>Consider these two functions:
```
template <typename T, typename U>
XY<T, U>
xy1(X, Y y)
{
return XY<T, U>{};
}
template <typename T, typename U>
XY<T, U>
xy2(X, Y)
{
return XY<T, U>{};
}
```
Note the absence of parameter names in the second function template.
Using this config
```
BasedOnStyle: LLVM
AlwaysBreakAfterReturnType: All
AlwaysBreakTemplateDeclarations: Yes
BreakBeforeBraces: Allman
```
the formatter ignores the `AlwaysBreakAfterReturnType`:
```
template <typename T, typename U>
XY<T, U>
xy1(X, Y y)
{
return XY<T, U>{};
}
template <typename T, typename U>
XY<T, U> xy2(X, Y)
{
return XY<T, U>{};
}
```
It gets more extreme when dropping the `AlwaysBreakTemplateDeclarations` rule.
```
BasedOnStyle: LLVM
AlwaysBreakAfterReturnType: All
BreakBeforeBraces: Allman
```
The formatter now yields completely different results for the two functions:
```
template <typename T, typename U>
XY<T, U>
xy1(X, Y y)
{
return XY<T, U>{};
}
template <typename T, typename U> XY<T, U> xy2(X, Y) { return XY<T, U>{}; }
```
