Huh that is weird, it works correctly in gdc but i can 
reproduce in dmd and ldc. And removing the debug keyword makes 
it work. Certainly smells like a regression bug to me.


Yep, apparently a v2.094 frontend regression (the 
`catch(Exception)` in the debug block is removed from the AST):

Is this a known DMD bug or feature?


```d
void f(T)(int num)
{
writefln("recognized %d as %s", num, T.stringof);
}

void main()
{
try
{
throw new Exception("");
}
catch (Exception)
{
f!Exception(1);
}
catch (Throwable)
{
f!Throwable(1);
}

debug
{
try
{
throw new Exception("");
}
catch (Exception)
{
f!Exception(2);
}
catch (Throwable)
{
f!Throwable(2);
}
}
}

// prints
// recognized 1 as Exception
// recognized 2 as Throwable
```
