# The `convert_to(value, type)` is a convenience function that does the same as `new(type, value)`.
# The difference in the argument ordering allows it to be used in chained style for
# improved readability "left to right".
#
# When the function is given a lambda, it is called with the converted value, and the function
# returns what the lambda returns, otherwise the converted value.
#
# @example 'convert_to' instead of 'new'
#
# ```puppet
# # The harder to read variant:
# # Using new operator - that is "calling the type" with operator ()
# Hash(Array("abc").map |$i,$v| { [$i, $v] })
#
# # The easier to read variant:
# # using 'convert_to'
# "abc".convert_to(Array).map |$i,$v| { [$i, $v] }.convert_to(Hash)
# ```
#
# @since 5.4.0
#
