Idle feature idea (sparked by these tweets on "the power of the dot: what I envy about OOP").

I want to mimic the obj.<tab> behaviour of OOP editors (like vscode-python or IPython), as it is extremely useful for exploring APIs and writing code:

For Julia, by example:

using FilePaths
dir = p"~/subdir"
dir|

, and then pressing some shortcut key would show:

absolute
chown
cp
exists
⋮

i.e. we call

methodswith(typeof(dir), supertypes=true)

, and suitably present the results, and make them iteratively filterable.
The methodswith call should probably be cached, as it's often rather slow.

Same idea could be done in IJulia.
