Thanks Duncan, Martin:
Please ignore my remarks about "top-level Windows context". I made a
mistake.
After correcting my mistake Duncan's suggestion worked, and the solution is
very similar to what the DLLpath argument of dyn.load() does: Sys.setenv()

be used to edit PATH so that Windows finds

I am certainly not an expert in S4 and know enough to be dangerous.
That being said, I used setMethod() as Romain had done. I would defer to others
with greater experience as to the pros and cons, including the risk of
confusion, but here is one approach, extending the example in ?slot:
setClas
I do not want to access the slot itself but its content: a:toto would be
a...@slot1[['toto']].
The thing is that I would like to have two different methods: '$' (that
I already have) and another one to define, ideally that behaves like '$'.
So in brief:
- a:toto would be for a...@slot1[['toto']]
You were, in effect, trying to overload the ":" operator, which is of course
for defining sequences.
If you are using S4 methods, what is wrong with using the default "@" as the
extraction syntax (eg. a...@name) to get at slots?
See ?"@" and ?slot

Alright.
Maybe the symbol I chose was not appropriate. I tried ':' to be able to
do 'a:name' with 'a' a S4 object.
I get the following error:
Error in genericForPrimitive(f) :
methods may not be defined for primitive function ":" in this version
of R
Does there exist any symbol that would b

No, the parser handles a fixed syntax, and that expression is not
legal. You could do it with
a %$$% name
using the infix operator syntax.

No. This is not grammatically valid syntax:

Dear R developers,
The slow performance of serializing to a raw vector on Windows is an
issue that has appeared in this list before. It appears to be due to
the frequent use of realloc from the resize_buffer method in
serialize.c.
I suggest a more granular, but still incremental, re-allocation
