 ## Syntax
 
-Tables are written using `{}` curly braces with `:` colons associating key
+Tables are written using `{}` curly braces with `=` equals signs associating key
 expressions with value expressions and commas between entries:
 
 ```tomo
-table := {"A": 10, "B": 20}
+table := {"A"=10, "B"=20}
 ```
 
 Empty tables must specify the key and value types explicitly:
 
 ```tomo
-empty := {:Text,Int}
+empty := {:Text=Int}
 ```
 
 For type annotations, a table that maps keys with type `K` to values of type
