-# 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-  assets:aaa    -10 AAA @ $10  ; cost selects the lot withdrawn from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 {}.
