module providing low-level manipulation of Perl data
DescriptionData::Peek is a module that allows for low-level manipulation of Perl data structures, particularly for displaying the internal representation of given Perl variables. In particular, it allows one to look at a scalar value to determine whether it contains a string (PV), integer (IV or UV) or floating point number (NV); the reference count of that scalar (REFCOUNT) and other flags (such as whether the string is UTF-8). This module can also create triple variables, which are similar to the dual variables provided by Scalar::Util - they have two or three values, and the value which is returned depends on the context in which it is used.
