VAR
Combined from primary sources listed below.

In Metaobject protocol (MOP)§

See primary documentation in context for VAR.

Returns the underlying Scalar object, if there is one.

The presence of a Scalar object indicates that the object is "itemized".

.say for (1, 2, 3);           # OUTPUT: «1␤2␤3␤», not itemized
.say for $(1, 2, 3);          # OUTPUT: «(1 2 3)␤», itemized
say (1, 2, 3).VAR ~~ Scalar;  # OUTPUT: «False␤»
say $(1, 2, 3).VAR ~~ Scalar; # OUTPUT: «True␤»

Please refer to the section on item context for more information.
