Velocity Template Language's set directive requires a variable on the left hand side. This doesn't work.
#set ( $entries.add("d") )
Even though I have no use for the return value of
add("d"), I have to assign it to a variable.
#set ( $x = $entries.add("d") )
I want to communicate that the variable is necessary, but I have no intention of using it later. Is there a convention for naming variables that only exist to appease the compiler?
