I don't know if it'll work, but you *might* be able to do something like
this:
$php_package_1 = 'php${php_version}-xml' #single quoted to prevent
interpolation
$install_versions.each | String $php_version | {
$php_install_1 = "${php_package_1}" #double quoted to now interpolate
ensure_packages($php_install_1, {ensure => present})
}
But this is a mess of reusing variables names.
Oh, you could also store the list of packages to be installed in Hiera, so
that you have one list, but you can reference it in two different places
(outside, and inside the loop).
