Examples

#import "std/containers"
using containers

dim q as LinkedList( of ustring )
q.PushBack( "a" ) : q.PushBack( "b" )

print q.Front( )         '' a -- peek without removing
print q.Count            '' 2, unchanged

'' Returns BYREF, so it assigns in place

'' reference has to refer to something. Check IsEmpty first.
