Provide more highlight options

[ronisbr]

First of all, thanks for this amazing package! The support of Julia in Emacs is pretty good :)

However, I think there is a point that can be improved. For example, take a look at the following figure. To the left, there is a .jl file opened in Emacs, whereas, to the right, there is the same file opened in Vim.

Notice that Julia mode in Vim has many more highlight options compared to Emacs. It highlights operation symbols like +, -, = and also literals. I think it is a little bit better.

Question: is it possible to add those options in Emacs?

Please, forget about this. I enabled number highlighting using the package highlight-numbers and emacs was really slow when opening files with a lot of numbers.

It's certainly possible and might even be more efficient than what you experienced with highlight-numbers. Could you take a look at https://www.gnu.org/software/emacs/manual/html_node/elisp/Faces-for-Font-Lock.html and let me know which faces you'd like for these different kinds of highlighting?

Nice! This is what I get with highlight-numbers:

I think it is pretty good. It uses (AFAIK) font-lock-constant-face for the numbers. For the symbols, I would propose font-lock-type-face, which seems to be the same font used for begin and end.
