ignoring the "inline"
There are 3 styles (ignoring the names of identifiers used), can think of
1) function
x := IfThen(a,b,c);
2) statement with return value
x := If a Then b else c;
3) ternary operator
having 3 arguments, it needs at least 2 tokens to separate them
x := a IfThen b else c;
Of course the operator can have a leading token, and the statement
syntax could be an operator.
In cases 2 and 3 (operator) precedences become an issue (unless a
terminating "end" is required)
x := If a Then b else c + 3;
should be which
x := (If a Then b else c) + 3;
x := If a Then b else (c + 3);
So function style has the build in clarity on this. But it can be
confused with existing functions of the same name.
