Note that any operation that returns NO_OUTPUT must
return the same singleton object from getNoOutput()
.

add(T prefix,
T output) |
Eg add("foo", "bar") -> "foobar"
|
abstract T |
common(T output1,
T output2) |
Eg common("foo", "foobar") -> "foo"

getNoOutput() |
NOTE: this output is compared with == so you must
ensure that all methods return the single object if
it's really no output
