Not sure how homoiconicity is related to this at all. Macros don't seem involved.
But I do think s-expressions are an improvement over HTML in certain scenarios.
That said (talking to OP now), why is the control handler outside the button?
In actual HTML, we have [button onclick="codeToBeEvaled()"]
In this thing, you have [button][onclick [sub-expressions]]
With s-expressions, at least you have some semblance of function calls,
which would make control flow operators seem slightly more natural,
but this hybrid of semantic and syntactic choice just seems bizarrely limited.
