How do I assign a function to a value in Scala?
While I feel like an unforgivable-horrible person to present this as an official answer, I am doing this as requested by the OP.
This problem can be solved like this:
def foo = println("foo") val fnRef = () => foo
or, as some other brave soul said, before deleting his answer:
def foo = println("foo") val fnRef = foo _
The second is perhaps a little preferable
since mine (the first) is a bit hackish and actually creates a completely new function that just calls an existing function when it is applied, whereas the latter is mostly a partial or deferred application of an existing function , because being semantically identical, the latter is more-idiomatic Scala (as Rex Kerr points out).
