Overview

An import declaration states that the current package depends on the functionality of the imported package and wants access to its name space. Thus, the current package gains access to the exported identifiers exposed by the imported package.

...
import [package-name-alias] "package-path-string-literal"
...

Example

...
import "lib/math"

The package path is enclosed in double quotes, it is a string literal.

The package-name-alias is optional. If not specified, the package will be referred as the last segment of the path.
