Description

It is currently difficult to determine if a hash contains a certain key.

Until #8705 is resolved, we need a method that can take a hash and determine if it has a certain key.

I propose that we introduce the method has_key

if has_key({}, 'key') {
  # should never get here
}

    (#8708) Add has_key function
    
    It is difficult to use existance of keys in a hash
    as a boolean condition in Puppet (see #8705)
    
    This function provides a working solution until
    the underlying issue in Puppet can be resolved.

I have similar version:

has_key.rb

Plus “has_value” as well:

has_value.rb

I will work on adding it to the standard library.
