Pearls before swine could be abbreviated PBS
I have these mental shorthands, e.g., OPC for other people's code/children, so when a wise suggestion is ignored, I thought, pearls before swine, but the acronym PBS is already taken.
Maybe it's an inside joke?

Being able to mark in an alias definition a point of minimal abbreviation, an old feature of VAX/VMS shell (DCL) would be really nice in modern *nix shells.
In DCL you used to be able to define an alias (in its own weird syntax) which would be something like this:

TIMES(2) System Calls Manual TIMES(2)
NAME
times - get process times
SYNOPSIS
#include <sys/types.h>
#include <sys/times.h>
#include <time.h>
int times(struct tms *buffer)
DESCRIPTION
Times returns time-accounting information for the current process and for the terminated child processes of the current process. All times
are in 1/CLOCKS_PER_SEC seconds.
This is the structure returned by times:
struct tms {
clock_t tms_utime; /* user time for this process */
clock_t tms_stime; /* system time for this process */
clock_t tms_cutime; /* children's user time */
clock_t tms_cstime; /* children's system time */
};
The user time is the number of clock ticks used by a process on its own computations. The system time is the number of clock ticks spent
inside the kernel on behalf of a process. This does not include time spent waiting for I/O to happen, only actual CPU instruction times.
The children times are the sum of the children's process times and their children's times.
RETURN
Times returns 0 on success, otherwise -1 with the error code stored into the global variable errno.
ERRORS
The following error code may be set in errno:
[EFAULT] The address specified by the buffer parameter is not in a valid part of the process address space.
