I am trying to use `std.process.environment.get()` as described
here: https://dlang.org/library/std/process/environment.get.html
I wrote this program to test it:
```d
import std.stdio;
import std.process;
int main(string[] args)
{
string home = environment.get("HOME");
writeln("home is ", home);
return 0;
}
```
But it fails to compile:
```
$ ldc2 -of environment environment.d
environment.d(6): Error: template `object.get` cannot deduce
function from argument types `!()(string)`
/usr/lib/ldc/x86_64-linux-gnu/include/d/object.d(3230):
Candidates are: `get(K, V)(inout(V[K]) aa, K key, lazy inout(V)
defaultValue)`
/usr/lib/ldc/x86_64-linux-gnu/include/d/object.d(3237):
`get(K, V)(inout(V[K])* aa, K key, lazy inout(V)
defaultValue)`
```
It works, though, to switch to a static import of `std.process`:
```d
import std.stdio;
static import std.process;
int main(string[] args)
{
string home = std.process.environment.get("HOME");
writeln("home is ", home);
return 0;
}
```
Why? What am I doing wrong in the first version that does not use
the `static import`?
My ldc2 version:
```
$ ldc2 -version
