I think its a good improvement. Only proposal I can make is to get rid
of the expr="" and just put it in quotes.
For example:
<%@ index(Album, Songs, ShowSongs) %>
album: <% Album %><br/>
<et:if "ShowSongs">
songs:<br/>
<et:map "S <- Songs">
song: <% S %><br/>
</et:map>
</et:if>
If you are at improving ErlTL I would like to see some whitespace
handling. As a designer I have a fetish for well looking html sources
and whats spit out right now doesn´t make me cheer.
