get rid off all the shit on bits of paper in my life (no particular order).
I'm relying on google to index all these pages
array := var :@FM is faster than array<-1>
loop remove .. is faster than x= array<i>
btree_extract is 20% faster than RLIST
p1 = item[1,'*'] p2 = item[-1,"*B"] p3 = FIELD(item,"*",1) either of these 2 forms are as fast p4 = FIELD(item,"*",2)
