Here’s a library from Mattt Thompson that uses a feature allowing you to use symbols are custom operators providing an implementation for many different math symbols.

In total there are over 40 symbols implemented within Euler.

You can find Euler on Github here.

Note that using these symbols is currently undocumented (only usage of the / = – + * % <> ! & | ^ . ~ symbols as custom operators is currently documented) so you may want to hold from using Euler for production use until it is.
