When doing a regular expression you have to do 3 at least lines of code

matcher := Regex <|<regexp>|>.matcher(<matchto>)
matcher.matches
<res> := matcher.group(<group num>)

while in for example in python you can just do

<res> = re.search(<regexp>, <matchto>).group(<group num>)

So I suggest the addition of function "match" to the Regex class, which would allow to do the following

<res> := Regex <|<regexp>|>.match(<matchto>).group(<group num>)

and with the power of fantrom in case there is no match

<res> := Regex <|<regexp>|>.match(<matchto>).?group(<group num>)

Not that we shouldn't consider a convenience method, but you can actually do it all with one line of code:

Regex<|...|>.matcher("....") { matches }.group(num)

sorry, but thanks for the answer
