Hello!

When an expression involves remove or removeAt and the same base array is involved in another expression the resulti is wrong and looks like the remove function performed mutation on its parameter.

using std.remove

local a = [0,1,2,3];
std.remove(a,0)+a

returns
[ 1, 2, 3, 1, 2, 3, 3]

while I expect the result to be [ 1, 2, 3, 0, 1, 2, 3 ]

using std.removeAt

local a = ['quux','foo','bar'];
std.removeAt(a,0)+a

returns [ "foo", "bar", "foo", "bar", "bar" ]
where I expect [ "foo", "bar", "quux", "foo", "bar" ]

cpp-jsonnet seems not to be affected by this issue and it looks like it doesn't happen if the removed element is the last of the array

This happens on released version 0.21 (the others didn't have remove/removeAt)
