"lambda"s are (as well as any static Python code) compiled at
load time -- independent of their position.
When you move the "lambda" to the top level, then the "lambda" object, too,
is build at load time. Otherwise, the object is build when the
function containing the "lambda" reaches the lambda.
However, construction this object from the predefined pieces is not
