## Operator and function semantics * Functions are often pass-throughs straight to the system-standard Go libraries. * The `min` and `max` functions are different from other multi-argument functions which return null if any of their inputs are null: for `min` and `max`, by contrast, if one argument is absent-null, the other is returned. Empty-null loses min or max against numeric or boolean; empty-null is less than any other string. * Symmetrically with respect to the bitwise OR, XOR, and AND operators `|`, `^`, `&`, Miller has logical operators `||`, `^^`, `&&`: the logical XOR not existing in Go. * The exponentiation operator `**` is familiar from many languages. * The regex-match and regex-not-match operators `=~` and `!=~` are similar to those in Ruby and Perl.
