What I'd like is being able to type in a big search textbox sth like:<p>"java try catch syntax"<p>and it would automatically (without me hitting enter) fetch the sample code and display it in a nice syntax-highlighted manner. It should also offer auto-completion like Google (eg. after I typed "java try"...).<p>Or:<p>"php class syntax"
"svn ignore files"
"diff show side by side"
"c++ template function"
etc.<p>It'd be a lot of work but it seems doable and it'd be a killer destination site for programmers.
