on IDEs (Integrated Development Environments)
Nowadays IDEs show which right parenthesis or brace matches which left one. They should at least do the following two things:
- Instead of showing just the one on the right or left of the caret, show both.
-- Even better, they should color every left one with different color, and color the right one with the color of whichever left it's ending. For example, the first left parenthesis can always be red and I can thus know I should put right parenthesis until I get to the red one.
