a bash bug that made me pull out some hair, for anyone that cares

Code:
#!/bin/bash

x[0]="zero"
x[1]="one"
x[2]="two"

print () {
echo "param 1: \"$1\""
echo "param 2: \"$2\""
echo "param 3: \"$3\""
}

echo "first form:"
print "test 1: ${x[@]}"


echo "second form:"
y="${x[@]}"
print "test 2: $y"


you expect:

Code:
first form:
param 1: "test 1: zero one two"
param 2: ""
param 3: ""
second form:
param 1: "test 2: zero one two"
param 2: ""
param 3: ""


and you get:

Code:
first form:
param 1: "test 1: zero"
param 2: "one"
param 3: "two"
second form:
param 1: "test 2: zero one two"
param 2: ""
param 3: ""


it seems when you use ${variable[@]} inside a string, and pass it to a function, it tries to split out the array elements into the different function parameters, even though it's all in quotes.
