in PLT, one can get hold of the value associated with an identifier

(module geiser scheme (export foo) ---)
calling
(dynamic-require ''geiser 'foo)
from anywhere returns the value of `foo, so, if it's a procedure, one
can call it without requiring the `geiser' module:
((dynamic-require ''geiser 'foo) arg)
guile has an equivalent form, dubbed @... is there a similar mechanism
in ikarus?

Ikarus allows local/internal imports.

Let's import it inside a 'let':

(import (srfi :1))
iota)
#<procedure iota [char 14435 of /scheme/srfi/%3a1/lists.sls]>
And it's still not visible at the top level:
