ExtractFilePath/ExtractFileName sounds more related to file operations, so:
Core.File:
...
TFile = class sealed(TObject)
public
class function ExtractPath ... ; static;
class function ExtractName ... ; static;
...
writeln(TFile.ExtractPath(...));
writeln(TFile.ExtractName(...));
or:
Core.File:
...
function ExtractPath ...;
function ExtractName ...;
writeln(File.ExtractPath(...));
writeln(File.ExtractName(...));
(btw the example above needs the -NS feature)
IMHO, if the <context> already is called "file", you don't need to add the
context name again in the function name, so instead of:
writeln(Extract<File>Path(...));
writeln(Extract<File>Path(...));
just use:
writeln(<File>.ExtractPath(...));
writeln(<File>.ExtractName(...));
So, you can do <context>.code-completation to get all the features to this
context.

Both approaches compiles, but I agree the it is a preferencial thing.
