Perl uses gt,lt,ge,le,eq,ne as string comparisons whereas
>,<,>=,<=,==,!= are used for numeric comparisons. Perl needs both by
design. You could reuse the same names.
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)
Pd too has that freedom for its built-in functions but also has the
ability to load a subset of all imaginable functions as externals. The
limitation lies in the inability of the various operating systems to
accept files named using arbitrary combinations of the available
character set. All of the OSs that I know of can handle regular a-z type
characters, so I suggest sticking to that range for the names of externals.
That's all.
