18964	[Patch] MapCSS rules using index are slow	GerdP	team	"For the validator we have several rules like this:
{{{
#!mapcss
way >[index=1] node,
way >[index=-1] node {
  set first_last_node;
}
}}}
The current implementation for the index test works like this:
Perform a sequential search for the given node in the parent way. If found, compare the position with the value given with index. 
I think it should work the other way around: Check if the node at the given position exists and if so compare it with the given node."	enhancement	closed	minor	20.03	Core validator		fixed	validator mapcss performance
