Sorry, I'm rather ignorant when it comes to this, but why
can't we use
[pegged](https://github.com/PhilippeSigaud/Pegged) to
transpile C++ code to D? Then we won't need a nogc compatible
std library and so many other things could get easier, like
getting legacy code to use Dlang. It might not be worth it for
C+17 and beyond, but older codebases could benefit
significantly, right?
I'm guessing it's hard because of the grammar
Well, still a grammar, though it was my little WTF moment.
for example this C++ grammar(often used in STL) where min is
simple minimum function
```cpp
float min(float l, float r)
{
return (l < r) ? l : r;
}
```
```cpp
float foo(float a, float b) {
return (min)(a,b);
}
```
and this direct translation to D doesn't works
```d
float foo(float a, float b) {
return (min)(a,b); // Error: C style cast illegal, use
`cast(min)(a , b)`
}
```
but this does
```d
float foo(float a, float b) {
return (&min)(a,b); // ok
}
```
