G'day Rolf,

I have a whole series of functions and aliases of the form perlX, where X is a lowercase letter. Here's a couple of examples.

This one I use almost every day. It's been in my toolbox since the mid '90s. It probably started as a simple contraction of perl -e; then -e became -E; strict and warnings were added; and so on. The -MCarp::Always is a fairly recent addition. 

$ alias perle
alias perle='perl -Mstrict -Mwarnings -Mautodie=:all -MCarp::Always -E
+'

This one's for Unicode work. 

$ alias perlu
alias perlu='perl -Mstrict -Mwarnings -Mautodie=:all -Mutf8 -C -E'

[download]

These are all for my own personal use. As I've added more over the years, some obvious letters were already taken so alternative (less obvious) ones were used. Only having to remember a single letter is easy for me and not confusing at all; in fact, it's mostly muscle memory. Remembering the historical reasoning behind the choice of a letter is far less important and, in some cases, gets forgotten.

Addendum: It looks like you've hard-coded the "less confusing" link to https://perlmonks.org/?node_id=11133350. Following that link puts me in a logged-out (Anonymous Monk) state. Please fix by changing that to [id://11133350|less confusing].
