Hi, PerlMonks. I am seeking wisdom about the shift()-> idiom. What does this do? I understand how shift operates in the context of an array, but this form seems to either be dereferencing a hash/array ref or calling a method. Specifically, I found this form of shift in the source code to Geo::Shapefile, e.g.


sub read_shx_header {shift()->read_shx_shp_header('shx',@_);}

Just curious if someone could shed some light on the use of shift in this context

Thanks
