To my (untrained) eye, the downside to the vanilla if block to me eye is that the hierarchical structure of the html (haml) is perverted by the if clause control flow. The 99% of the time, %div really wants to be directly underneath the containing element, not underneath the silent-eval if, imho.
I guess it seems slightly odd to me that &= and != and == get special treatment as syntactic sugar, but this other (common?) case does not. After all, we could use the argument to require = h(foo) in lieu of &=, != etc. I appreciate everyone's feedback tho - clearly there isn't a groundswell of interest in this addition :-). I can easily live eith the status quo or the :conditional_tag(:div) which fits on a single line and mostly serves my needs just fine. On Jul 19, 4:32 pm, "G.
