Scripts can return some values (like functions).
For example, we have foo.pashm:
# ...
return 'hello world'
Now, if i import this file:
$output = import('foo.pashm')
println 'output: ' + $output
Output:
output: hello world
As you can see, function import (or import_once, import_run…) will return the returned value
by command return in the script. By this feature, we can return values by scripts like functions.
