+Add support for `block`, `msg`, `chain`, and `tx` properties:
+```
+block.coinbase: address
+block.difficulty: u256
+block.number: u256
+block.timestamp: u256
+chain.id: u256
+msg.value: u256
+tx.gas_price: u256
+tx.origin: address
+```
+(Note that `msg.sender: address` was added previously.)
+
+Example:
+```
+def post_fork() -> bool:
+    return block.number > 2675000
+```
