398# _dotop($root, $item, \@args, $lvalue)

400# This is the core 'dot' operation method which evaluates elements of
401# variables against their root. All variables have an implicit root
402# which is the stash object itself (a hash). Thus, a non-compound
403# variable 'foo' is actually '(stash.)foo', the compound 'foo.bar' is
404# '(stash.)foo.bar'. The first parameter is a reference to the current
405# root, initially the stash itself. The second parameter contains the
406# name of the variable element, e.g. 'foo'. The third optional
407# parameter is a reference to a list of any parenthesised arguments
408# specified for the variable, which are passed to sub-routines, object
409# methods, etc. The final parameter is an optional flag to indicate
410# if this variable is being evaluated on the left side of an assignment
411# (e.g. foo.bar.baz = 10). When set true, intermediated hashes will
412# be created (e.g. bar) if necessary.
413#
414# Returns the result of evaluating the item against the root, having
415# performed any variable "magic". The value returned can then be used
416# as the root of the next _dotop() in a compound sequence. Returns
417# undef if the variable is undefined.
