capture avoidance

I am interested in a clarification of the description in the document


"http://tcl.tk/man/tcl8.5/TclCmd/regexp.htm".


Does the compilation of regular expressions adjust the generated code


to the case if no "subMatchVar" is specified for a function call?


- Is an optimization or conversion to "non-capturing parentheses"


performed?


- Is a single character "(" implicitly treated as if it would be


replaced by the string "(?:" at the appropriate places?



Regards,


Markus
