You've given us what looks like a perfectly plain English sentence; if
its meaning is not plain from context (which I find hard to believe)
then you should also provide the context so we stand a chance of being
able to help.

What on Earth does "helps retain the value of variable across child
modules" mean?

`:- import_module foo' makes the names defined in module foo visible in
the importing module.

`:- include_module foo' declares module foo to be a (separate)
sub-module of the module making the declaration.  It does not imply that
foo is imported, however.
