Commenting out whole sections of code incredibly useful for debugging and rapid prototyping.

  Many editors allow you to select the section and line-comment it as a whole.

    Exactly. In java, block comments are used at the beginning of a class or method for javadoc generation. If I want to comment out big portions of code, I use line-comment thanks to eclipse. With this working practice, the problem does not exist. Never use block comments for commenting out big portions of code.

    Even vim has a visual block selection mode. <ctrl-v> at the top of the block, then move down (j or down arrow) to the bottom. That marks the block. Then type the I character (insert in front of cursor), type the comment character, and press <esc>. Once you press <esc>, the inserted comment character action is repeated for the whole block. Or non-visual block select...V% with cursor on the opening {.

      Oh, my :vmap <M-/> :s|^|//|<CR> :vmap <M-\> :s|^//||<CR> (writing from memory, may need tuning)

    Equally importantly, block commenting fucks with the editor's ability to comment/uncomment code.
