; <rekado>davidl: a syntax checker probably wouldn’t help you here. “invalid field specifier” means that you have a record (e.g. operating-system) and you try to initialise a field that doesn’t exist.
; <rekado>davidl: this can mean that you close an expression too early, which makes it seem that its contents are fields for the parent expression.
; <rekado>davidl: but without more context it’s hard to say what’s wrong in your case.
