> mixed foo(mixed x){return x?(write("FOO\n"),"FOO"):werror("BAR\n");}
> foo(1);
FOO
Result: 1
> foo(0);
BAR
Result: 0
> mixed fooo(mixed x){return
x?(write("FOO\n"),"FOO"):(werror("BAR\n"),"BAR");}
> fooo(0);
BAR
Result: "BAR"
> fooo(1);
FOO
Result: "FOO"Note that while fooo() works correctly, the return value of foo(1) is bogus. Pike is getting confused when the third arg of the ternary operator (the `c' in a?b:c) is a call to a function of return type void.
