+# Lots, again
+
+2023-01
+
+I believe one could emulate most of ledger/beancount's lot tracking/selection with simpler syntax, just @.
+
+Eg, with today's explicit lot subaccounts:
+
+```journal
+2022-01-01 buy at 10
+  assets:aaa:_20220101     10 AAA @ $10
+  assets:cash           -$100
+    
+2022-02-01 buy at 12
+  assets:aaa:_20220201     10 AAA @ $12
+  assets:cash           -$120
+    
+2022-03-01 sell at 15
+  assets:aaa:_20220101    -10 AAA @ $10  ; original cost basis
+  assets:aaa:_20220201     -5 AAA @ $12
+  assets:cash            $225
+  revenues:gains         $-65
+```
+
+Or with support for automatic or no lot subaccounts:
+
+```journal
+2022-01-01 buy at 10
+  assets:aaa     10 AAA @ $10  ; creates a new lot subaccount automatically, perhaps hidden by default
+  assets:cash           -$100
+    
+2022-02-01 buy at 12
+  assets:aaa     10 AAA @ $12  ; or just a new lot internally, with special commands to show it, like ledger/beancount
+  assets:cash           -$120
+    
+2022-03-01 sell at 15
+  assets:aaa    -10 AAA @ $10  ; cost selects the lot withdrawn from
+  assets:aaa     -5 AAA @ $12  ; other selectors like date/note would be possible
+  assets:cash            $225
+  revenues:gains         $-65
+```
+
+I don't see much need for {}.
