Thanks, you helped me to find the issue. The productive coding 
looks like this:

import std.algorithm : all;

void main()
{
     import std.ascii : isAlpha, isDigit;
     assert("abc123".all!(c => (c.isAlpha && c.isUpper == false) 
|| c.isDigit));
}

With previous dmd version, although import isUpper was not 
defined, somehow it worked.
This seems to be fixed now. This issue was the missing isUpper 
import statement.
The error message is a little bit odd:
Error: static assert:  "_lambda isn't a unary predicate function 
for range.front"

Kind regards
André
