I will refer to my explanation because down-to-earth has always been my
goal. I hope i succeeded:
leyts try very rough simlified concept:
template itself - is compile-time program (parameterizable), it
can generate some code for you.
template instantiation (like "calling") with "!" - instruct
compiler to "start this compile-time program here with this
parameters".

A template can be seen as a static struct too, so you can

Create an object of type `FilterResult!(unaryFun!predicate,
Range)` by passing `range` to its ctor, then return that object.
