To improve the following syntax:  
filter(x → occursin(r"(?i).jpg|.png", x), readdir())  
into  
readdir(_.jpg|_.png)

Good, It is same to the glob in Perl.  
BTW, Is it better to implant it into the Julia base package

Not really. If it’s in julia Base it can only be updated with a new version of Julia. If it’s in a package, it can be updated at any time. Things that do not have to be in base will rarely be put in base.
