I think one of the things I dislike about c++ the most, is that passing value by reference is invisible at the callsite.

@jfbastien I dare you to create a mode where passing by reference requires a @ or $ sigil or anything really, &&& for all I care.

@pedantcoder Couldn't this be fixed "easily enough" in the dev environment by coloring/font-face-changing the arguments to a call?
