Imagine for a moment, the following:
trait UnicodeOrdered {
def < (that: Any): Boolean = (this < that)
def ≤ (that: Any): Boolean = (this < that) || (this == that)
def > (that: Any): Boolean = !(this ≤ that)
def ≥ (that: Any): Boolean = (this > that) || (this == that)
}
def < (that: Any): Boolean = (this < that)
def ≤ (that: Any): Boolean = (this < that) || (this == that)
def > (that: Any): Boolean = !(this ≤ that)
def ≥ (that: Any): Boolean = (this > that) || (this == that)
}
This is a cool feature, useful in the implementation of DSL’s, in Scala.
