There is at minimum a documentation bug (the docs don't discuss
whether or how to interpolate hash values) and a bug / needed feature
regarding the extremely unhelpful error message. I'm not sure whether
it's supposed to work to interpolate a hash value as you are
attempting to do (and I don't recall offhand whether you can
interpolate array elements either), but supporting that is at least a
viable feature request.
In the mean time, there are at least two workarounds I can think of.
One is to use an inline template to do your interpolation, and another
is to copy the hash value into an ordinary variable and then
interpolate that. I would personally prefer the latter in most
circumstances; I find it clearer, especially if I need the hash value
more than once:
$theme_name = $theme['name']
# Site theme
drupal6::theme-repo { "${name}-${theme_name}":
}
Note also that there's a better solution for your simplified example,
where the string you want is exactly the hash value: just omit the
quotes. To wit,
foo::bar { $some_hash['name']: }
