That is called 'Array Notation'. All ColdFusion variables are now
structures AKA 'Associative Array' or 'Hash' or many other names. But
it means that you can dynamically reference the elements of complex
variables by using the square brackets eliminating 99.78% the need to
use evaluate.
form[fieldName] is the same as evaluate('form.#fieldName#')
This is also very useful when there are illegal variable names
involved. This sometimes happens with forms, but is not uncommon with
more complex XML structures.
I.E. #form.my field# is illegal if rather unlikely. But it could be
achieved with #form["my field"]#.
