Delphi compatibility. But as the example shows you could use it for 
LINQ-like functionality as well.

Delphi compatibility (or as is written for that entry: compatibility to 
other Pascal compilers in general). This won't have any negative impact 
on logical expressions. Also keep in mind that comparisons with "= True" 
could lead to wrong results anyway as "True" for Boolean and friends is 
"1" while "True" for ByteBool and friends is any non-zero value.
