You cannot turn any programmer into a disciplined programmer just by
giving him a well designed language. I you try so, they will not like to
use that language, will leave that language as soon as possible or they
try to adapt the language to their style of programming.

People who are used to weak typing will use a type like
data Number = Int Int | Float Float | ...
for numbers, or even String for everything, they will use numbers, where
enumerations are more appropriate and so on.

New programmers want example programs and libraries to learn style and
tricks. The higher the portion of ill-designed libraries, the harder it is
too find good examples.
In my experience only the other way round works: Let people use C, Perl
and Python until they find their programs unmaintainable. Then they will
become interested in style and discipline and programming languages which
_support_ good style.
