Python allows for multi-*line* lambda:
lambda key, value, condition, sep='', default='': (
compute_prefix(key)
+ sep.join([str(expression or default)
for obj in lookup(key, value)
if condition(obj)]
)
+ compute_suffix(key)
)
What it doesn't allow is multi-*statement* lambda; lambda is limited to
a single expression.
Although I have heard from Ruby enthusiasts that the ability to write
large, complex, multi-statement anonymous block functions is really
useful, its not something I can personally say I have missed.
I think that once you get past a fairly simple one-line expression,
anything else ought to be tested; and that requires making it a named
function at the top level so that doctest or unittest can see it.
