I also prefer to test predicates at the end of a line: it makes it read more like a conversation. For example:
if ($DEBUG) { print STDERR "Debug: some value"; }
is pretty clear, but if we re-write that one line, it becomes more of a conversation with the maintainer:
print STDERR "Debug: some value" if $DEBUG;
Notice how well it flows in English: do this if that is very much what we say to one another all day in the real world. If this that is very much how one expects a computer to talk, not a real person.

Really? I frequently encounter

if( $Going_by_the_grocery_store ) { pickup_milk(); } or if( $in_my_town ) { meet_for_beer(); }
Perhaps a regional difference in speaking patterns.

[Corion]: Meh. I think I have now the parts down that I want from a simple Javascript frontend for single-page- applications with a aPerl backend. But it seems that all Javascript templating modules either don't support two-way binding (which would be nice) or ...
[Corion]: ... don't support server-side precompilation (which means the client has to compile all templates to Javascript themselves), or are giant frameworks that expect to do everything (which is not what I want)
[Corion]: I feel that there is a talk somewhere in there, either about the structure and parts, or how I used several parts to get a complete whole.
[Corion]: Maybe I can still find something that is compatible with handlebars.js (which has JS precompilation) but allows for two-way data binding (which is great for the UI)
