Future ideas
============

Global HSL Shifting / Contrast Shifting?
----------------------------------------

Unsure how useful this would be in the real world, but switching between some
machines can render some colourschemes differently, because their screens
or terminals are different.

The idea would be you could set a global shift on HSL to effect all colours
that are pushed through it.

In actuality, I think what I *really* want is a contrast scale, which isn't as
simple as simply "make it all brighter" or "make it all bluer".

**Automatic Property Inference**
----------------------------

Would allow for syntax like:

```lua
-- automatically infer appropriate key (Normal.fg)
CursorLine { fg = Normal, bg = Visual }
```

Most of this code is actually already present, but the ability to write
`fg = Normal` tends to encourage `fg = Normal.ro(...)` at a later time,
is an invalid operation.

Without a uniform solution to this, I'm reticent to "muddy" the API.

For now, you must write `fg = Normal.fg`.
