Regex matching

Suggestion: Could regex be incorporated in the matcher?

One immediate use case in ABAP is an end of line comment `"` is OK and `"` in strings need to be kept, but a line starting with `"` or `*` should be skipped.

```ABAP
* Now we will loop through the table
loop at sometable reference into data(row).
if row->somefield = 'foo'.
"Exclude these
continue.
endif.
write / |Row { sy-tabix } contains "{ row->anotherfield }"|.
endloop. "end-of line comments can be deleted or not...
```

Should go to
```ABAP
loop at sometable reference into data(row).
if row->somefield = 'foo'.
continue.
endif.
write / |Row { sy-tabix } contains "{ row->anotherfield }"|.
endloop. "end-of line comments can be deleted or not...
```

Easy to do with regex, but I can't see a way according to the current documentation.
