In pragmatic assignment-writing terms, cutesy features don't get you extra marks, but the probabilistic expectation is that they will lose you marks on average, because they will introduce bugs which affect the working of the non-cutesy parts of the program.

That is to say: Wield your cleverness cleverly. Don't waste your cleverness in doing silly things.

Two pithy quotations:

"The superior pilot uses his superior judgement to avoid situations in which he has to demonstrate his superior skill." (traditional pilot saying)

"Debugging is twice as hard as writing the code in the first place. Therefore, if you write the code as cleverly as possible, you are, by definition, not smart enough to debug it." — Brian Kernighan
