Regex split ignoore empty and whitespace

[AlphaPurned via Digitalmars-d-learn]

std.regex.split(l, ctRegex!`[\s-\)\(\.]`);

I'm trying too split a string on spaces and stuff... but it is 
returning empty strings and other matches(e.g., ()).

I realize I can delete afterwards but is there a direct way from 
split or ctRegex?
