Hello.
Consider this code
void main()
{
l:
{
int v;
}
v = 5; // ok, v is defined
}
As I understand from D's grammar this behaviour is not a bug as
LabeledStatement:
Identifier : NoScopeStatement
and NoScopeStatement in turn takes BlockStatement without creating new
scope.
It looks very unnatural for me though. Especially when label goes before
ThenStatement
if(1)
l1:{
int v;
}
v = 5;
it works as above, yet label after 'while'
while(1)
l1:{
int v;
}
v = 5; // error, v is undefined
has no such effect, even if ThenStatement is just another ScopeStatement.
I don't understand this difference. Any rationale behind this?
