Import declaration
An import declaration imports variables, functions, and classes
from another source file.
It allows only the named import using the following syntax.
import { abs, max } from './math.bs'
This imports functions abs and max declared in the source file
./math.bs.
These functions must be declared with the export modifier.
Furthermore, the import type declaration is a valid syntax in BlueScript,
but this declaration is ignored.
import type { integer, float } from './types.ts'
This declaration is useful when using a TypeScript editor for editing a BlueScript program.
The builtin types integer and float will
be treated as valid type names when the contents of ./types.ts are as follows.
export type integer = number
export type float = number
