Fail to declare 2-dimensional generic array

Summary

Declaring a generic two-dimensional array fails when using the array[dim1,dim2] syntax. Using array[dim1] of array[dim2], however, works.

System Information

• Operating system: Windows 8.1
• Processor architecture: x86-64
• Compiler version: trunk
• Device: Computer

Steps to reproduce

See example.

Example Project

program Project1;

{$mode objfpc}

type generic TMatrix4<T> = array[0..3] of array [0..3] of T; // works
type generic TAnotherMatrix4<T> = array[0..3,0..3] of T; // "Identifier not found T"

begin
end.

What is the current bug behavior?

The declaration type generic TAnotherMatrix4<T> = array[0..3,0..3] of T fails with an Identifier not found "T" error.

What is the expected (correct) behavior?

The declaration should succeed.
