`if` with `module` doesn't work

[amitu]

When trying the following:

-- login-page:
lang if { lang == "hi" }: hi
lang: en


-- component login-page:
module lang: en

.. body omitted
-- end: login-page

I am getting:

fastn-Error: path: slides/scenarios/login-page/, PackageError { message: "failed to 
parse ParseError { message: \"Expected one value for `module` type argument `lang`, 
found  `2` values\", doc_id: \"ui.fifthtry.com/slides/pages/login\", line_number: 16 }" }
