There are many different bad designs in programming languages. i was wondering which language has implemented most the best programming language features from different languages.
For the German colloquialism challenged (adapted from a GT translation):
An egg-laying wool milk sow is a colloquial expression that describes something (a thing, person or problem solution) that "only has advantages, satisfies all needs, meets all requirements"
(still waiting for "ADD ONE TO COBOL GIVING COBOL", myself)
