When I wrote computer code in school, programming as we kids called it, I could literally watch my programs compile on the screen. Working on a Radio Shack TRS-80 in PASCAL, we would see the lines of code scroll by, 3 or 4 a second, as they compiled into executable code. When that is the speed of the computer checking your work, you learn very quickly to proofread your code from syntax or logic errors. A simple semicolon on the wrong place can result in quite a bit of lost time.

At some point we transitioned to Turbo Pascal, which compiled hundreds of lines in a split second, on par with the speed of today's compilers, which are often working through thousands of lines of code. Is that a good thing, however? Has this speed improvement ended up building poor habits in developers?
