It's an old and annoying bug. Could be a duplicate but I failed to find any.

Sample:

struct SimpleCaseEntry
{
    ubyte bucket;// n - number in bucket
     property ubyte size()
    {
        return bucket & 0x3F;
    }
     property auto isLower()
    {
        return bucket & 0x40;
    }
     property auto isUpper()
    {
        return bucket & 0x80;
    }
    this(ubyte size, bool lower, bool upper)
    {
        bucket = size;
        if(lower)
            bucket |= 0x40;
        if(upper)
            bucket |= 0x80;

    }
}

void main()
{
    const SimpleCaseEntry e = SimpleCaseEntry(8, true, false);
    assert(!e.isUpper);
    assert(e.isLower);
}

With dmd 2.060:

D:\D\m.d(30): Error: function m.SimpleCaseEntry.isUpper () is not callable
using argument types()
D:\D\m.d(31): Error: function m.SimpleCaseEntry.isLower () is not callable
using argument types ()

Not a single word mentioning CONST or QUALIFIERS. While I'm more or less used
to wrong error message it would blow away newibie's mind and thus marked as
major.

See Issue 8549

(But maybe both are dupes of an older bug report of mine)

Seems fixed in latest git head:

$ dmd test.d
test.d(30): Error: mutable method test.SimpleCaseEntry.isUpper is not callable
using a const object
test.d(31): Error: mutable method test.SimpleCaseEntry.isLower is not callable
using a const object

(In reply to comment #2)

 Seems fixed in latest git head:
 
 $ dmd test.d
 test.d(30): Error: mutable method test.SimpleCaseEntry.isUpper is not callable
 using a const object
 test.d(31): Error: mutable method test.SimpleCaseEntry.isLower is not callable
 using a const object


The lack of information about qualifier mismatching is fixed by bug 6707.
After that, the error message is improved by fixing bug 1730.

Both are fixed in 2.061.
