On this I completely agree. Most problems are down to inexperienced
developers rather than poor tools.
Having said that, if the tool makers find that certain things can be
improved to make them less likely to be abused by these developers, then
it may be worth it. This is the case with Java's break & continue, in
that they are 'like' a goto, but have tight constraints upon how and
when they can be used.
