Guards - list supported operators

[rokf]

Hi,

Currently the description in the Guards lesson of the tour says the following:

Only a limited set of operators can be used in guards, and functions cannot be called at all.

Source: https://tour.gleam.run/flow-control/guards/

Could (should) we list the supported operators or link to an external resource where there's an up-to-date list of them?

Cheers!

Good idea!

Hi,
I was recently asked this same question on exercism's gleam track. From the compiler source code I gathered that the following are allowed:

• integer, float and boolean operators
• access to variables and constants
• access to tuple and record contents (thru index/field)
• access to public members of an imported module

I am no rust programmer so this would have to be confirmed.
