# Description
this pr condenses `MutBuiltinVar`, `LetBuiltinVar` and `ConstBuiltinVar`
into one error:
```nu
Error: nu::parser::name_is_builtin_var
× `in` used as variable name.
╭─[entry #69:1:1]
1 │ let in = 420
· ─┬
· ╰── already a builtin variable
╰────
help: 'in' is the name of a builtin Nushell variable and cannot be used
as a variable name
```
it also fixes this case which was previously not handled
```nu
let $nu = 420 # this variable would have been 'lost'
```
