A word about operators

• You may have the impression that Perl 6 is operator crazy
• If so, you are right
• Part of the Perl 6 philosophy is to have a very rich set of operators
• It's up to programmers not to abuse this
• eg As an infix, + (by itself) should always refer to mathematical addition
• prefix:<+> is just sugar for calling an object's Numeric conversion method
• Operators which start with + are numeric operators
• For instance, +& converts both its arguments to Int and does bitwise AND on them
• prefix:<?> is sugar for .Bool, and ?| converts its arguments to Bool and ORs them
• prefix:<~> is sugar for .Str, conversion to a string
