"Error: incompatible types" although types are the same

Description

The following program gives the error "xt.d(14): Error: incompatible types for ((&toString) is (&toString)): 'char[] function()' and 'char[] function()'"

class X {

char[] toString() {

return "";

}

}

bool foo;

void main() {

char[] function() f = &X.toString; char[] function() g = &Object.toString; foo = f is g; //following line doesn't work foo = &X.toString is &Object.toString; //line 14

} <<<

But as you can see from the code above line 14, the types definitely are the same.

Looks like the ticket system removed some newlines, which destroyed formatting of the code sample. Here is it again: 

class X {
    char[] toString() {
        return "";
    }
}

bool foo;

void main() {
    char[] function() f = &X.toString;
    char[] function() g = &Object.toString;
    foo = f is g;
    //following line doesn't work
    foo = &X.toString is &Object.toString; //line 14
}
