catch any stray method call inside DSL block

def method_missing(name, *_args)
  raise_syntax_error(
    "unknown DSL keyword `#{name}`. Valid top-level keywords are: " \
    "input, value, let, trait, ref, fn, literal, select, index, import, codegen.",

Instance Method Details

#guard_rails_caller_location ⇒ Object

The user’s DSL line that triggered the stray call. Stray keywords can fire before any DSL method set @context.current_location, so we read the caller stack directly instead of trusting the stored location.
