Compilation error due to declaring an already declared symbol
class X::Redeclaration does X::Comp { }
Thrown when a symbol (variable, routine, type, parameter, ...) 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;
dies with
===SORRY!=== Redeclaration of symbol $x
It works with routines too:
sub f() { }
sub f() { }
dies with
===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
}
Returns the name of the symbol that was redeclared.
Returns the kind of symbol that was redeclared. Usually symbol, but can also be routine, type etc.
Returns a string that is attached to the end of the error message. It usually explains the particular problem in more detail, or suggests way to fix the problem.
