Cantor is mentioned, but I'd also mention the idea that some infinities are equivalent (e.g. Integers and Rationals), but others are not (Rationals and Real numbers).

Does StorX have any special handling of concurrent writes, or would the user need to take care of that?

TNG introduced various civilisations that drive much of the plot in DS9.

Season 1: Ferengi

Season 4: Trill, Cardassians

Season 5: Bajorans

Also, Chief O'Brien and his wife Keiko who were recurring minor characters in TNG have more important roles in DS9.

I remember in a previous job having to enable git rerere, otherwise it wouldn't remember previously resolved conflicts.

Do you mean local variables per se, or mutable local variables? Clojure, like most Lisps has let.

That syntax suggests the first pair will be flipped, and the rest will just be as they were, i.e. more like flip_first

Consider

    % perl -v | head -2

    This is perl 5, version 40, subversion 0 (v5.40.0) built for x86_64-linux
    % 
    % perl -E 'use feature "switch"; my ($x, $y); given ($x) { $y = 1 when /^abc/ }'
    given is deprecated at -e line 1.
    when is deprecated at -e line 1.

This is also mentioned in the docs:

  Smartmatch is now seen as a failed experiment and was marked as deprecated in Perl 5.37.10. 
  This includes the when and given keywords, as well as the smartmatch operator ~~. 
  The feature will be removed entirely in the Perl 5.42.0 production release.

>> In python you can't tell whats a variable and whats a list, and whats a dictionary by looking.

In Perl, sigils are used to distinguish between scalars/lists/hashes. Sigils and references are not the same thing.

The key idea in CLOS is multi method dispatch, which Moose does not provide.

Moose out of the box has its own set of problems, leading to other workarounds, e.g.

Moo (a similar but much less bloated solution)

MooseX::Extended - Moose with more sensible/correct defaults
