module Puppet::Parser::Functions

Validate that all passed values are string data structures. Abort catalog
compilation if any value fails this check.
The following values will pass:
$my_string = "one two"
validate_string($my_string, 'three')
The following values will fail, causing compilation to abort:
validate_string(true)
validate_string([ 'some', 'array' ])
$undefined = undef
validate_string($undefined)
ENDHEREDOC

unless arg.is_a?(String)
raise Puppet::ParseError, ("#{arg.inspect} is not a string. It looks to be a #{arg.class}")
