Best way to to go into LatexGroupNodes?

Congratulations on thank you for this magnificent tool!

I was wondering whether a recursive function is needed to parse LatexGroupNodes?

E.g.

def traverse(node):
    #Parsing for enumerate environments
        if node.isNodeType(LatexEnvironmentNode) and node.environmentname == "enumerate":
           
[omitted]
                   
#check for enumeration nested within LatexGroupNodes
        if node.isNodeType(LatexGroupNode): #Recurse into groupnodes
            traverse(node)

#loop through nodes 
for node in nodes:
    traverse(node)

If so, what's the best approach to avoid infinite recursion?
