> Sometimes it's helpful to select the serialized size of a column/cell for debugging purposes.
> Having a function like {{len(x)}} that accepts every type and just returns the serialized
size would be helpful and is more readable than pages of raw text or even blob output in cqlsh.
> Such a function could take a whole column and also individual elements of non-frozen
collections.
> With such a function, one can build a UDA that produces a histogram over multiple CQL
rows. But that's just an add-on that people can build (not considered for this ticket).
