In terms of the package keyword itself, :: and main are distinct packages, and :::: is another package entirely...

$ perl -Mstrict -Mwarnings -E'package main; say __PACKAGE__' main $ perl -Mstrict -Mwarnings -E'package ::main; say __PACKAGE__' main $ perl -Mstrict -Mwarnings -E'package ::; say __PACKAGE__' :: $ perl -Mstrict -Mwarnings -E'package ::::; say __PACKAGE__' ::::
{ package main; sub xxx { 0 }; package ::; sub xxx { 1 }; package ::::; sub xxx { 2 }; } use 5.010; say ::xxx(); # 0 say ::::xxx(); # 1 say ::::::xxx(); # 2
perl -E'sub Monkey::do{say$_,for@_,do{($monkey=[caller(0)]->[3])=~s{::}{ }and$monkey}}"Monkey say"->Monkey::do'

    [LanX]: efficient survey
    [MidLifeXis]: And under MINGW64_NT-6.1 MYHOST 2.6.0(0.304/5/3) 2016-09-09 09:46 x86_64 Msys there seem to be issues with escapes in external build tool calls.
    [Corion]: I mean, it's a technical feat it achieves, but... why? ;)
    [MidLifeXis]: And it also has the 0.14 version of the tarball in its manifest.
    [LanX]: avoiding unreadable brackets
    [MidLifeXis]: Although the previous one could be a b0rken PATH, I would need to dig for that.
    [thezip]: I've got to go to meetings now. If anyone has further comments regarding Spreadsheet::XLSX deployment to Strawberry Perl 5.24.1, please /msg me -- thanks!

    LanX ... darn ... where is my car?
