Enables forwarding mixed trusted/untrusted concatenated data that can be sanitized at the point of use, when the sanitization requirements are known, instead of at the point of input.

Examples:
With Pasteur this classic sql injection code
sql << pstr / "select email from demo.useremails where username = " + name + " and type=" + emailType;
is *automatically* converted into a parameterized sql query

This os injection code
System(pstr / "ping " + hostname)
automatically sanitizes the hostname parameter.
