{{{

sage: A

sage: B
B
sage: function('C, D')
(C, D)
sage: C

sage: D

}}}
IMHO {{{function('C, D')}}} should work, i.e., the function {{{D}}} should
be injected into the workspace.
The corresponding command with {{{var}}} works:
{{{
sage: var('c, d')
(c, d)
sage: c
c
sage: d
d
}}}
Further, the following works:
{{{
sage: C, D = function('C, D')
sage: C
C
sage: D
D
}}}
This might also be related with the additional spacing, which occurs in
the following:
{{{
sage: C, D = function('C, D')
sage: C(D(x))
C( D(x))
}}}
(the space in {{{C( D(x))}}}, which should also be corrected (removed).
