I guess I just got used to saying things like:

x++

in PHP and Java land. But when I tried this in my Rails code it had a fit:

compile error

/users/gshankar/projects/naplan/app/views/answers/new.html.haml:23: syntax error, unexpected kENSURE, expecting kEND

/users/gshankar/projects/naplan/app/views/answers/new.html.haml:26: syntax error, unexpected $end, expecting kEND

I googled around a bit for Ruby/Rails operators for a reference to ++ but couldn’t find anything. For a language which focuses on writing less I find it a bit strange that there wouldn’t be a ++ equivalent. Am I missing something?
