'skip' symbol in fxrc file

[aladdin-selmi]

The skip symbol is very handy in terminal but I can't find a way to use it in fxrc.js file.

Here is an example that's working in terminal. (It's filtering my local branches to delete)

git branch -l | fx -r '/develop|master|main/.test(x) ? skip : x'

My js helper looks like this :

global.git = {
  unused: x => /develop|master|main/.test(x) ? Symbol.for('skip') : x
}

I tried Symbol.for('skip'), but it seems that the symbol as a return type is not supported.
Here is the full error anyway :

/private/var/folders/_6/crjkb7cj5jndcn1vx3rbrvpm0000gn/T/fx-34.0.0.js:648
    throw new Error(`Unsupported value type: ${typeof value}`)
          ^

Error: Unsupported value type: symbol

    at async main (/private/var/folders/_6/crjkb7cj5jndcn1vx3rbrvpm0000gn/T/fx-34.0.0.js:59:7)

Does anyone know how to access that symbol or output the equivalent (do nothing) ?
Thanks

I think skip is not initialized in fxrc yet. We need to move skip symbol upper and add it to globalThis.
