OK, I've found out by using "apt-cache policy package-name": I need to
lower the default priorities of packages from testing other than guile
with

Package: *
Pin: release o=Debian
Pin-Priority: 10

Now I do not get other packages with "aptitude full-upgrade", but if I
pull in guile-2.0 from testing it wants to change several other
libraries:

$ sudo aptitude -t testing full-upgrade guile-2.0
The following NEW packages will be installed:
  libffi6{a}
The following packages will be upgraded:
  guile-2.0 guile-2.0-libs libc6 libgc1c2 libgssapi-krb5-2
libk5crypto3 libkeyutils1
  libkrb5-3 libkrb5support0 libtirpc1 locales nfs-common
12 packages upgraded, 1 newly installed, 0 to remove and 1353 not upgraded.
Need to get 12.1 MB of archives. After unpacking 2,553 kB will be used.
The following packages have unmet dependencies:
 krb5-user : Depends: libkrb5-3 (= 1.10.1+dfsg-5+deb7u2) but
1.12.1+dfsg-9 is to be installed.
 libgc-dev : Depends: libgc1c2 (= 1:7.1-9.1) but 1:7.2d-6.3 is to be installed.
 libc6-i386 : Depends: libc6 (= 2.13-38+deb7u4) but 2.19-11 is to be installed.
 guile-2.0-dev : Depends: guile-2.0 (= 2.0.5+1-3) but 2.0.11+1-1 is to
be installed.
 libc6-dev : Depends: libc6 (= 2.13-38+deb7u4) but 2.19-11 is to be installed.
 libc-dev-bin : Depends: libc6 (< 2.14) but 2.19-11 is to be installed.

I think I will just install guile 2.0.11 "manually".

Thanks for all the help!
