Even the !FALSE trick doesn't work:
if (x == TRUE)…
if (x) …
Still give different results
This proves again that if you try to use booleans, you better use them as booleans, ie. in
the second style.
In Java too, I groan when I see
if (b == true)
because it is verbose, distracting, redundant.
And I saw many newbies just forgetting the difference between = and ==:
if (b = true)
and wondering why the test doesn't work. In Java, that's the only case where an assignment
in a test is legal. In C, it can be worse...
Now, I agree that
isn't super-readable, alas. That's where the choice of ~ for negation is good, it stands
out more... :-)
