The braces are not necessary here.
Are braced incorrect here? I've been putting braces around all
variable names, so that there are fewer syntax exceptions for me to
remember...
They are not incorrect, just unnecessary.
The only time they are necessary is when the variable name is followed
by a character that is legal in a variable name.
Or when modifying the output of the variable expansion.
