Why can't Groovy regex matchers be negated?

Can anyone explain the following?

println('x' ==~ /x/)
println('x' !=~ /x/)

result:

true
true

There is no !=~ operator in groovy. It's a combination of != and ~.

println('x' !=~ /x/)

is equivalent to

println('x' != (~ /x/))

What you need is

println(!('x' ==~ /x/))
