10.4.1+ Custom Managed Records usable?

I like clarity. Brevity is not always clarity.

IMO the only true way to do this in pascal is as they done in Oxygene - see "if expressions": https://docs.elementscompiler.com/Oxygene/Delphi/NewFeatures/

The If and Case statements expressions are indeed pretty nice.

We already have if and case statements in Delphi, we don't have expressions though. Expressions are parts of statements.

 

Speaking of Oxygene, don't forget to mention colon operator, lambda expressions, for loop expressions, async & await (.NET only) expressions and more ...

 

See also this Q&A that relates to the topic discussed in this thread - ternary conditional operator,  null-coalescing operator (Elvis operator) and Oxygene colon operator:

Escape from chain of Assigned() in Delphi

It also provides some QP links of feature requests.

I wouldn't refactor code only to now use inline variable declarations either.

Why not?

IMHO the only true way to do this in pascal is as they've done in Python... like Oxygene, except Oxygene reversed it for for some reason.

 

ilabel = 'Item' if ilist.Count == 1 else 'Items'

If I'm not missing anything, Oxygene didn't "reverse" it, but kept it consistent with Pascal.

I don't think that rings true. I mean the Python if statement is the same as the Pascal if statement. 

 

The Python syntax is closer to natural language than what is done in Oxygene. I don't see either as being particularly in keeping with Pascal, one way or another.

Looks like Perl to me, only with less special characters.

It's Python. Perl's conditional operator is the same as C. That looks completely different. And has the condition first. Quote unlike how it is done in Python. 

[dummzeuch 1505]

It just reminded me of conditional execution of statements with appended conditions:

 

DoSomething if condition

 

I don't remember the specifics. I rarely program in Perl nowadays.

Ah, yes, I see now!
