Edge case of where command

[blindFS]

The following code is valid in nu but causes error in tree-sitter-nu

[{a: {b: true}}, {a: {d: false}}] | where a?.b?

However the following code is not allowed in nushell

[{a: {b: true}}, {a: {d: false}}] | where a?.b? and a?.b?

Error: nu::shell::type_mismatch

  × Type mismatch.
   ╭─[entry #38:1:46]

   ·                                              ┬

   ╰────

So which of the following way is suggested for its fix in tree-sitter-nu:

1. special treatment to make only the first case valid
2. allow both

Seems like both of those should be where condition == true vs just where condition but maybe it's a bug in nushell?

I'm not sure, that usage is not present in the doc of where, but I've seen it somewhere in nu_scripts.

In my opinion, if we'd like to be able to save some effort when the column is itself a boolean, we should allow both cases.

Or simply don't allow any of those.

I can understand that. I've asked the core-team what they think about it too.
