Re^4: ::'s role in strings

I'm not surprised at all. Double quoted strings are bad in some shells, as '$a' might be processed by the shell, not by perl, therefore, might result in a shell error.

$ perl -v

This is perl, v5.8.6 built for darwin-thread-multi-2level
(with 2 registered patches, see perl -V for more detail)

...

$ perl -e "$a = Class::; print $a"
syntax error at -e line 1, near "="
Execution of -e aborted due to compilation errors.
$ perl -e '$a = Class::; print $a'
Class

Double quoted strings are bad in shells, as '$a' might be processed by the shell, That bit is false. Double quotes are required by my shell. `$` does not have a special meaning for it, and single-quoting the argument does not work. Your statement should read: Double quoted strings are bad in some shells, as '$a' is processed by them, I'm sure you're right that double-quoted strings are bad for his shell (and it, not `perl`, produced the error he posted).
