Motivation

As I said in #562 , we can enhance the constructor of string_type to support conversion of other types (integer, real, logical, complex) to string_type, and support format argument.

The important thing is that this constructor can be elemental, type(string_type) is very good at constructing flexible string arrays, but to_string can only be pure because character(:), allcoatable.

At this stage, string_type only constructs strings from character, integer, and logical types.

Prior Art

• interface string_type (elemental)
• interface to_string (pure)
