See the Sequences node of the Gdb manual.  The syntax is quite restricted and
expressions like $kld->filename won't work.

There is currently work being done on Python scripting.  This is being reported
on the gdb mailing list (gdb@sourceware.org) which is where this question should
really go as it's about Gdb.
