(Side note: Using %% is enough to escape it)

Yeah, that's true.  It's doing something special since it's
essentially delaying evaluation.  It's almost sort of a simplistic
lambda, but for strings.  If I were to do the same thing in erb,

"#{expanded} \#{delayed}"

would become:

"<%= expanded %> <%%= delayed %>"

The double % should give you same pause that \ does.

I am somehow loath to mix both syntaxes, although I realise that's an
option.  I don't really know why I would want to use one syntax to
partially build a template and another syntax to build the rest.

Hehe!  Thanks a lot for the info.  I'll have to think about this and
play around with a few of them.
