NAME
Coercions::void - Coercion to Void.SYNOPSIS
Void void( a x )ARGUMENTS
x The value to discard
DESCRIPTION
Coerces any value to Void (i.e. discards it), usually used for discarding the result of a function. For example, the HTMLDocument(3kaya) functions for adding elements to the tree return the element just added, which is often not necessary.
p = addParagraph(doc.body,"Hello ");
void(appendInlineElement(p,StrongEmphasis,"World!"));
Another use is in discarding the return value from database update queries
