Where pertinent, the 'dot' functions (operators prefaced with a period), like .split(), can be chained together. If an operator's parentheses are normally optional, they be omitted if that operator has another operator chained to its right. Thus:
$MyList.sort().reverse() GOOD
$MyList.sort().reverse GOOD
$MyList.sort.reverse() GOOD
$MyList.sort.reverse GOOD
"Where pertinent" points to the fact that the dot operators used must act on compatible data types:
$MyList.sort().reverse() GOOD
$MyColor.red().empty() BAD
It is most likely that opportunities for chaining only occur in relation to text data functions though do be aware that some text dot operators are only fro lists/sets and some only for string even though others cover both types of data.
It is possible to chain to parentheses:
(Hello" +" "+"world").size
The above example is trivial but shows the general principle. In practice, the technique can become useful is the expression is complex and requires Tinderbox to fully evaluate it before processing the chained function.
