const
A: TVec3F = (X: 1.2; Y: 2.4; Z: 3.8);
B: TVec3F = (X: 2.1; Y: 4.2; Z: 8.3);
// You can't do the next part currently, obviously
C: TVec3F = A + B;
D: TVec3F = A - B;
E: TVec3F = A * B;
F: TVec3F = A / B;
Sorry to say but, this should not work even with
*pure* function. Typed constants are not truly
constants.
Correct. Though considering that we're talking about *compile time* the
compiler *could* treat consts (in {$J-} mode) as constants if pure
functions are involved... Though it would need a bit more work as
currently the compiler is "simply" piping the constant values of typed
constants into the output assembly.

Sven
