and a bit about multiple inheritance in LPC - http://graphcomp.com/info/mud/mudos/lpc/constructs/inherit.h...
And another bit - http://www.geas.de/tutorial/lpc_57.html
As to seeing it in other languages... this gets into a mixing - https://en.wikipedia.org/wiki/Mixin
An example of that in Scala - https://docs.scala-lang.org/tour/mixin-class-composition.htm... or https://www.baeldung.com/scala/class-composition-mixins
The issue is that for most situations, the additional conceptual load of multiple inheritance gets difficult.
