> I think we can improve interactive use of PyArrow by making the repr of some basic types (Buffer, MemoryPool...) more informative.
> See this session for example:
> {code:python}
> >>> pool = pa.default_memory_pool()
> >>> pool
> <pyarrow.lib.MemoryPool at 0x7fea126982a0>
> >>> pool.backend_name
> 'jemalloc'
> >>> buf = pa.allocate_buffer(1024, memory_pool=pool)
> >>> buf
> <pyarrow.lib.Buffer at 0x7fea5e51e7b0>
> >>> buf.is_cpu
> True
> >>> buf.is_mutable
> True
> >>> buf.size
> 1024
> {code}
