Hi,
Looking at the
code<https://github.com/clojure/clojure/blob/master/src/jvm/clojure/lang/LazySeq.java>for
LazySeq.seq() I was wondering why a 'while' loop is used rather than an
'if' and a recursive call to ls.seq(), which would be cleaner code I guess?
Am I right to suspect this simply an optimization to avoid possible stack
overflow, or maybe for performance reasons, or is it some other reason?
final synchronized public ISeq seq(){
sval();
if(sv != null)
{
Object ls = sv;
sv = null;
while(ls instanceof LazySeq)
{
ls = ((LazySeq)ls).sval();
}
s = RT.seq(ls);
}
return s;
}
