e.g., instead of foo(a,b), we have foo_a_b.

Why not? This was a quick post-dinner pair programming project one lazy night, with Leah Hanson.

Support named arguments.

Make a macro that lets you declare variables and functions with arbitrary names, such as (, and , allowing names like (۶ૈ ᵒ̌ Дᵒ̌)۶ૈ=͟͟͞͞ ⌨. I don't know that this is possible without using quoted strings or modifying the parser, and it seems unlikely that Julia will accept a pull request that puts ʕ╯•ᴥ•ʔ╯︵‾‾ into the parser as a token that special cases the rest of the line up to some special delimeter. Oh well. Strings it is. This basically works, but these things need better testing and names.
