I believe, I understand `auto,' but of calling execute() on an 
array of strings..?

It is just UFCS which allows instead of:
```d
func(params)
```
write it in version:
```d
params.func
```

So in D (as it is very Elegant) you can write:
```d
4.writeln
```
and it will print "4"

When operating on an array, can I assume that it will return an 
array?:: auto x=["who","whoami"].execute

mm no..
it doesn't matter as function has 2 types
`OutType func(InputType x)`

You can have different types for input arguments and output 
arguments.
