Lambdas would merely be a syntactic sugar for anonymous functions with a 
bit of type inference sprinkled in. E.g. something like the following:

=== code begin ===

DoSomethingWithFunc(lambda (x, y) as x * y);

// as anonymous function:

DoSomethingWithFunc(function(x, y: LongInt): LongInt; begin result := x 
* y; end);

=== code end ===

The backing functionality for lambda's is already part of anonymous 
functions.
