|`<first(attr)>`|The first or only element of attr. You can combine operations to say things like first(rest(names)) to get second element.|
|`<length(attr)>`|Return the length of a mult-valued attribute or 1 if it is single attribute. If attribute is null return 0. Strings are not special; i.e., length("foo") is 1 meaning "1 attribute". Nulls are counted in lists so a list of 300 nulls is length 300. If you don't want to count nulls, use length(strip(list)).
|`<strlen(attr)>`|
Return the length of a string attribute; runtime error if not string.
|`<last(attr)>`|
The last or only element of attr.
|`<rest(attr)>`|
All but the first element of attr. Returns nothing if <attr> is single valued.
|`<reverse(attr)>`|
Return a list with the same elements as v but in reverse order. null values are NOT stripped out. use reverse(strip(v)) to do that.
|`<trunc(attr)>`|
returns all elements but last element
|`<strip(attr)>`|
Return a new list w/o null values.
