sub-sequenceは、posからはじまって、len個つづきます
The sub-sequence begins at offset pos within the String object and continues for len characters.

String::operator ()()

Synopsis: #include <string.hpp>
public:
String String::operator ()( size_t pos, size_t len ) const;
Semantics: This form of the operator () public member function extracts a sub-sequence of characters from
the String object. A new String object is created that contains the sub-sequence of characters.
The sub-sequence begins at offset pos within the String object and continues for len characters. The
first character of a String object is at position zero.
If pos is greater than or equal to the length of the String object, the result is empty.
If len is such that pos + len exceeds the length of the object, the result is the sub-sequence of characters
from the String object starting at offset pos and running to the end of the String object.
Results: The operator () public member function returns a String object.
See Also: String::operator [], operator char, operator char const *
