scala - How to return a stream of the first N Fibonacci numbers? -

i'm trying return stream of first n fibonacci n given parameter. lets if pass 6 function should "0,1,1,2,3,5" or if pass 7 should "0,1,1,2,3,5,8" , on. ideas on how accomplish this?.

here have far:

 def fibonacci(n: int): stream[int] = {    if (n == 0) return 0;     if (n<= 2) return 1;      fibterm = fibonacci(n - 1) + fibonacci(n - 2);     return fibterm;  } 

create fibonacci stream.

val fib: stream[int] = 0 #:: fib.scan(1)(_+_) 

take n elements it.

fib.take(n) 

here how can add in function:

def fibonacci(n: int): stream[int] = {    lazy val fib: stream[int] = 0 #:: fib.scan(1)(_+_)    fib.take(n) } 

note lazy needed otherwise compiler gets confused , gives: "<> error: forward reference extends on definition of value fib"
