I have a table and a function:

```
table:([] id:til 5; name:("one";"two";"three";"four";"five"))
fu:{[x] x,"_",x}

```

And I want to apply the function in an update statement on each row and set the result into a new column 'xyz'. How can I do that? 
This here does not work, as it seems to evaluate the argument as a list:

```
xyz:update x:fu[name] from table

```
