Description Denis Shelomovskii 2012-01-29 04:13:17 UTC 
---
synchronized int i; // should be definitely an error

if(true) int i;     // IMHO, should be an error
if(true) l: f();    // should be probably an error
---

Consider the following D code copied from C:
---
volatile int* p; // volatile statements deprecated; use synchronized statements instead
---
A one is forced to change `volatile` -> `synchronized` after brief look at the error and, if he will be unhappy enough, his program will compile.

Therefore a case with `if` looks lass common but still signalize about an error.
An it is an error in C# (like a variant with label probably because of possible `l: int i;` case): `error CS1023: Embedded statement cannot be a declaration or labeled statement`.

Also look at Issue 2197.
