Delphi SysUtils provides quite a few utility methods that ISLAND RTL currently does not.
For example, I didn’t find Delphi SysUtils.ExtractFileDir counterpart in Island RTL.
It is good that we have DelphiRTL to help convert legacy Delphi code - but my question is: for brand new Island application writing from scratch, in a situation like this, should I use DelphiRTL to mix with Island RTL for convenience, or should I write the pure-blood Island code meaning I may re-inventing wheels?
Sorry I guess this is not a technical questions, but a religious question. But I’d like to hear advice.
