Re^3: Distinguishing between an array of objects and an array of strings

There is a good reason for that.

$ perl -e'package 0'
syntax error at -e line 1, near "package 0"
Execution of -e aborted due to compilation errors.

Namespace names follow the same rules as variable names.

`0` is a perfectly valid variable name. `$0` is a well known variable - and @0 and %0 are valid as well. `0` is also valid as a package name - but like many other valid package names, you can't use it as an argument to `package`.	[reply]

No they don't. package declarations do, namespaces can be anything. `*{ anything } = \ anything; bless ..., anything;` [download]	[reply] [d/l]
