That is saying something completely different. My contention is that to the uninformed
@+ and $LAST_MATCH_END
- $? and $CHILD_ERROR
- $^C and $COMPILING
- $^T and $BASETIME
- $^I and $INPLACE_EDIT
- $" and $LIST_SEPARATOR
are all obscure. If you don't know that Perl has a list separator concept, the name $LIST_SEPARATOR leaves you to
look everywhere for its meaning. I would not know $^I
's meaning, but by understanding the naming convention, I know it is a token defined in perlvar; in some cases that may be enough to guess/remember its meaning because I don't need to consider concepts that come from the
problem, -- is $LIST_SEPARATOR part of user output
general programming, -- or is it about a data structure
host system, -- or is it about porting
or a specialty domain. -- or a bit of arcana from some lib
