Isn't it odd to read "curly" braces? Every printed dictionary I have, up through the 1990s at least, says that braces are {these}, brackets are [these], and parentheses are (these). Saying "curly brace" is as redundant as saying "round parentheses." Yes, braces are curly, by definition.
At least that's how it always in American English, and ASCII. Apparently British English says more than [these] can be "brackets" and <these> were called "angle brackets" in the 1970s, but when did anyone in the computer industry ever start calling anything but {these} braces?
