=TITLE class X::Redeclaration
class X::Redeclaration does X::Comp { }
Thrown when a symbol (variable, routine, type, paramater, ...) is redeclared.
Note that redeclarations are generally fine in an inner scope, but if the
redeclaration appears in the same scope as the original declaration,
it usually indicates an error and is treated as one.
Examples
my $x; my $x
===SORRY!===
Redeclaration of symbol $x
sub f() { }
sub f() { }
===SORRY!===
Redeclaration of routine f
But those are fine
my $x;
sub f() {
my $x; # not a redeclaration,
# because it's in an inner scope
sub f() { }; # same
}
