I’ve stumbled into this problem before while drafting a language I want to make*. A lot of the design philosophy is “symbols for language features” and as such import/export is handled by `<~`and `~>`. An example of an exported function:

``` <~ foo := (a: int) { a - 1 } ```

Then at the import site:

``` ~> foo ```

* some day it’ll totally for real make it off the page and into an interpreter I’m sure :,)
