<p>‘imports’ a string – converts a string to a Python object, importing
any necessary modules and evaluating the expression. Everything
before the : in an import expression is the module path; everything
after is an expression to be evaluated in the namespace of that
module.</p>
<p>Alternately, if no : is present, then import the modules and get the
attributes as necessary. Arbitrary expressions are not allowed in
that case.</p>
