DT:some decision table
input output?
key1 value1
key2 val2
$`map.key1` value1
$`1+2` 3

If an $`expression` appears in a cell (whether in a Decision Table, Script Table, or any other kind of table that can call functions) then that expression will be evaluated.

The first row above loads a hashtable in the symbol named map. The second row will valuate the expression map.key1 and return the expression's result (value1). The third row evaluates an expression that doesn't use a symbol that's stored.

You can combine symbols as follows:

$`map.key1` and $`1+2` come from expressions

Both expressions will be evaluated and replaced with their result values.
