Consider using predicative method calls for boolean methods

The predicative method call for boolean methods, e.g.

IF [ NOT ] condition_is_fulfilled( ).

is not just very compact, but it also allows to keep the code closer to natural language as the comparison expression:

" anti-pattern
IF condition_is_fulfilled( ) = abap_true / abap_false.

Mind that the predicative method call ... meth( ) ... is just a short form of ... meth( ) IS NOT INITIAL ..., see Predicative Method Call in the ABAP Keyword Documentation. This is why the short form should only be used for methods returning types where the non-initial value has the meaning of “true” and the initial value has the meaning of “false”.
