Option variable
maperror
Default value: true
When maperror
is false
, causes all of the mapping functions, for example
map (<span class="replaceable">f</span>, <span class="replaceable">expr_1</span>, <span class="replaceable">expr_2</span>, ...)
to (1) stop when they finish going down the shortest expr_i if not all of the expr_i are of the same length and (2) apply f to [expr_1, expr_2, ...] if the expr_i are not all the same type of object.
If maperror
is true
then an error message
is displayed in the above two instances.
