[fpc-devel] Readonly Memory Stream?

Hi,
sometimes I have to work with static fixed buffer in memory (for example
returned from external API), which I would like to behave like stream.
Then I define:
type TStaticMemoryStream = class(TCustomMemoryStream) end;
and in code I use for example:
MS := TStaticMemoryStream.Create;
MS.SetPointer(buffer, bufferLen);
MS.Position := 0;
Bitmap.LoadFromStream(MS);
MS.Free;
I know that it is only very few lines of code, but would it we worth to
extend capability of TMemoryStream in RTL to support for example
constructor like:
TMemoryStream.Create(buffer, bufferLen);
which will instantiate memory stream on fixed memory block without
possibility to Write?
Or introduce new TCustomMemoryStream descendant in RTL like my
TStaticMemoryStream() ?
Only question...
TIA
