 The following options control variable scope:
-- <code>-l</code> or <code>--local</code> forces the specified environment variable to be given a scope that is local to the current block, even if a variable with the given name exists and is non-local
-- <code>-g</code> or <code>--global</code> causes the specified environment variable to be given a global scope. Non-global variables disappear when the block they belong to ends
-- <code>-U</code> or <code>--universal</code> causes the specified environment variable to be given a universal scope. If this option is supplied, the variable will be shared between all the current users fish instances on the current computer, and will be preserved across restarts of the shell.
