Normally functions from other modules are used in a qualified fashion, with
the module qualifier before function name. For example,
io.println("Hello!").
It is also possible to specify a list of functions to import from a module in
an unqualified fashion, such as the println function in the code
editor. Because it has been imported like this it can be referred to as just
println.
Generally it is best to use qualified imports, as this makes it clear where the function is defined, making the code easier to read.
