The shell's [] (/usr/bin/test) also has -gt,-lt,-ge,-le,-eq,-ne, which it uses for numeric comparisons, whereas it uses >,<,>=,<=,==,!= for string comparisons. It also needs both by design.

Sure, but bash is written in c and it can call its functions whatever it likes because they are built into the program. (It will also try to interpret your file name if it isn't alphanumeric)

The reason why I listed those examples is not to say that you could just use the special punctuation instead of letters. I'm just pointing you to what looks like a standard notation for writing those same concepts as letters, so that you write >= as "ge" instead of "greaterthanorequal" or "greaterequal" or "greq" or any other long and nonstandard combination.

That's all I mean. Do you understand?
