Concatenates each object in +objects+ to +self+; returns +self+:
'foo'.concat('bar', 'baz') # => "foobarbaz"
For each given object +object+ that is an integer,
the value is considered a codepoint and converted to a character before concatenation:
'foo'.concat(32, 'bar', 32, 'baz') # => "foo bar baz" # Embeds spaces.
'те'.concat(1089, 1090) # => "тест"
'こん'.concat(12395, 12385, 12399) # => "こんにちは"
