Shouldn't the error message say 'length()'?
No, it should say length is a property, not a function. a.length should
work.
Note the error message here:
struct S
{
int x;
}
void main()
{
S s;
s.x();
}
function expected before (), not s.x of type int
Please file a bug report.

import std.stdio;

a["one"] = 1;
a["two"] = 2;
a["three"] = 3;
auto len = a.length();

Well, if we think of it as separate steps, resolving the function
"length" is what's failing here. The subsequent () would just
call it, if it existed, but the name of the property/symbol would
still be "length".
But yes; you could make a case that, in the case of invalid
function calls, it should include the whole erroneous attempted
function signature in the error message. I can imagine it
becoming ambiguous once templates enter the picture however, and
for not much gain.
