Minor quibble: I don't like having a hard exit followed by an "else".
If the "if" branch will unconditionally quit the loop (with a break,
here, but could also be a return, a thrown exception, etc etc), I
would prefer to see the "else" removed and its code unindented one
level. Maybe this is just personal preference, though, learned from
assembly language programming where a "block if" looks something like
this:
; if x == y:
CMP x,y
JNZ .else
; Code for "x == y"
JMP .endif
.else:
; Code for "else"
.endif
Putting an unconditional departure in the "x == y" branch makes the
"JMP .endif" redundant.
