Use a trick to prevent a type size mismatch warning to be generated by the
assignment node. First convert implicitly to the resulttype. This will insert
the range check. The Second conversion is done explicitly to hide the implicit conversion
for the assignment node and therefor preventing the warning (PFV) }
