It'll be handy, if Code Insight shows more related
functions/procedures according to current expression type. What I
mean?
For example:

type
    TCaption = string[23];
    TRec = record
    end;

function GetCaption(V:TCaption):boolean;
procedure ProcDo(const R:TRec);
procedure DatasetExport(D:TDataset);

....


var T:TCaption;
      R:TRec;
      C:TDataset;
begin
  ...
  T. // here we get Code Insight window, containing GetCaption
function
  R. // here we get Code Insight window, containing ProcDo procedure
  C. // here we get Code Insight window, containing DatasetExport
procedure

Hope, it is quite clear. Thanks

I don't know I i understand what you mean.
But since T in your example is not a record or class type, the syntax
with the dot is strange already.

You probably mean to get Information about all functions that take a
TCaption as parameter or result value?
But if T is a String or Integer this would return, well, a lot.
Probably it could be restricted to just the unit scope, but that would
be rather confusing as well.

Yes, you undertsood the idea. Syntax with dot is just just the place
where Code Insight might happen.

QuoteYou probably mean to get Information about all functions that
take a TCaption as parameter or result value?

Yes, you are right. I mean parameter(s).

QuoteBut if T is a String or Integer this would return, well, a lot.

Of course, such base types should be excluded.

QuoteProbably it could be restricted to just the unit scope, but that
would be rather confusing as well.

Restricting to unit scope is not good . You see, I specially gave an
example without base types. An example with TDataset is the most
general example of a situation.

Not every functionality may be added by inheritance (third-party
sources, inserting in the center of hierarchy, etc). At present, IDE
Code insight doesn't help.

Just one small thing: the Delphi IDE is by now that much overloaded
with code helping features that it generally takes more time to wait
for typed changes than to type them. It sometimes even crashed when
just moving the mouse over a field.

I really like that Lazarus is smaller on that account  And I don't
like code help on typing a dot at all (based on bad experiences with
Delphi). If this is on Ctrl+Space, well then, ok

Regarding unit scope: that could be arranged by order; methods of the
current unit coming first.

Anyway, I strongly disagree with your "At present, IDE Code insight
doesn't help". Speak for yourself only please

So, everybody agreed? Ok, now waiting for the final word.

You know, I meant IDE Code insight doesn't help described situations.

Not sure if anybody agreed. I don't want this feature, just making
things more and more complicated and prone to error.

I'll second CCRDude and Theo.
