The problem I have with them is in no way the looks, it is that they are not
strictly equivalent as they imply dictionary lookups. Which shows in
performance, eg
>>> import timeit
>>> timeit.Timer('[]').timeit()
0.22358344426456436
>>> timeit.Timer('list()').timeit()
0.54574505977715049
>>> timeit.Timer('{}').timeit()
0.21328632549668214
>>> timeit.Timer('dict()').timeit()
0.50557906102591232
