Inspired by yesterday's `units` discussion on @lobsters, I'm playing around with this in my zshrc:

```
function ___numbat { numbat -e "$*" }
aliases[=]='noglob ___numbat'
```

With that I can run most simple numbat expressions without escaping:

```
$ = 24 * 10
$ = 25mm to ft
$ = from_fahrenheit(212) to celsius
```

Expressions containing the pipe operator or function calls without arguments do need quoting, but it's still pretty cool.
