i would be happy with both ideas. the second proposal seems to be of 
better use in the field, if you are able to switch depending on the 
input file.

but still i think the code for the two delimiter-combinations should be 
the same for both ideas. means: the same piece of code should also for 
the compile-time option should work for the long <?ruby as well as for 
the short <%. am i clear?

thanks for the explanation. i could imagine the analogous escape 
sequence for <?ruby, namely <?ruby%. but still i did not think alot 
about that issue because even the idea of escaping ruby-code like that 
was new to me. at the moment i don't even see the use of that clearly.

i always liked the problem of extra newlines coming from nowhere in 
other languages like JSP, PHP, XSL and not really be able to do a lot 
against them ;-)
