¡Bienvenido (Bienvenida ?) a nuestro D Forum! Nos alegra mucho
tenerte con nosotros. Es obvio que no estás empezando, y estamos
seguros de que tu experiencia será de gran valor para todos. Pero

Welcome to the world of D. It's obvious you're not just starting
out. You will definitely get better with time. When I look at
your code snippets, the first lines usually start like this:
```d
#!/usr/bin/env dmd
import std;
alias print = writeln;
//...
```
I'm sure you chose the print alias for convenience. But you can
do something similar much more easily. Here it is:
```d
import std.stdio : print = writeln;
```
This way selective importing makes it easier to learn the
standard library and optimizes the compiled code in the best way
possible. For example, the following function is very enjoyable
to read:
```d
auto maxPow(ulong a, ulong b)
{
import std.math : pow;
import std.algorithm : min, max;
auto power = a.min(b);
return a.max(b).pow(power);
}
unittest
{
assert(maxPow(2, 5) == 25);
assert(maxPow(5, 2) == 25);
assert(maxPow(5, 0) == 1);
assert(maxPow(0, 5) == 1);
}
```
It may seem strange to you to use import lines inside functions,
here, there, everywhere. But rest assured, this experience will
provide you with advantages that are not available in almost any
other programming language.
Of course, the choice is yours, it is possible to make everything
much easier with `import std`. 😁
