 **Only float edge weights** Eventually we might support complex edge weight objects, but for now we only support 32bit floats.
 
+**Accessing nodes by their name is O(log2(n))** Internally, CSRGraphs' map of node names is a (binary searched) sorted array indexing into node ID. Since node names are accessed much more often than than node IDs by name, this is a worthy tradeoff, but it may be unexpected if you heavily use the `G[node_name]` operator.
