first bullet in the "Tips and Tricks" section under Dynamic Directive

The first bullet in the "Tips and Tricks" section under Dynamic Directive now reads:

"...virtual methods are faster and take up less memory..."

Should read:

"...virtual methods are faster but take up more memory..."

This is described correctly in the last paragraph on page 87.

Example of reintroduce

The example seems to imply that the TSingleVector class extends the TVector
class, but the declaration of TSingleVector does not mention TVector. Because
of this, the reintroduce keyword in the definition of TSingleVector.Add is
pointless.

The $M Compiler Directive might make a reference to the $TypeInfo Directive (on page 467), since it is $M+ or $M-. Just a suggestion.
