Py<Wrapper>

• PyIterable
• PyList
• PyDict
• PySet
• PyBuffer
  • General parsing of format strings.
  • Unaligned types.
  • Byte-reversed types.
• PyArray
  • Support the numpy array interface (__array__, __array_interface__).
  • Allow conversion to/from tuples containing python objects.
• PyPandasDataFrame
  • Tables interface
  • TableTraits interface
  • Customise column types and index
  • Convert pandas.core.indexes.range.RangeIndex to a StepRange{Int}?
• PyIO
  • Currently limited to byte-based IO and extremely slow. Perhaps need to manually buffer each way?
• PyObjectArray <: AbstractArray{PyObject}, represented as an array of CPyPtr, used by default as output of pyjulia(::AbstractArray).__array__().

pyjulia

• Sequence interface (tuples and vectors)
• Buffer protocol (strided arrays)
• Numpy array protocol (__array_interface__)
• Numpy array conversion (__array__) returning PyObjectArray by default unless __array_interface__ already supported.
• Generalize pytypestrformat to work on any type.
• Mapping interface (dicts, named tuples?)
• Set interface (sets)
• Number interface
• IO interface (IO=IOBase, then subclasses for raw, buffered and text IO)
• An argument parsing function or macro
• Separate pyjlraw from pyjl
• Have a BufferedIterator which iterates over 1024 (say) values at a time and saves them as a buffer of PyObject.

pyconvert

• dates, times
• ctypes
• to named tuple
• arrays (buffer protocol, array interface, and __array__)
• IO
• numbers
• numpy scalars (np.float32 etc)

Others

• README
• Documentation
• Logo
• Testing & CI
• Migrate CI away from Travis. GitHub Actions?
• Move configuration (finding libpython) all to run-time & dynamically load/cache function pointers as required.
• Multimedia display (MIMEs and corresponding _repr_MIME_ methods from ipython)
• Hook into Julia documentation system
• QT_PLUGIN_PATH hack
• GUI event loops to support interactive plotting (e.g. with matplotlib)
• @pyeval, @pyexec, py"..." for calling pyeval and pyexec with Julia value interpolation
• ?some_python_function should show the function name and signature
• Add GIL manipulation functions (pygiloff, pygilon, etc)
• When running inside an IPython kernel, change the default output display to go the kernel
• When running inside an IJulia kernel, change sys.stdout to go the the kernel
• When running inside an IPython or IJulia kernel, start up the other kind of kernel and link them together.
