Just looking at bound identifiers in different standards, we have:

        David Van Horn's "Essential Scheme", which binds 84 identifiers.

        R2RS, which binds 171 identifiers (not counting those which were
        removed in R3RS or R4RS).

        R3RS, which binds 178 identifiers (not counting those which were
        removed in R4RS).

        IEEE Scheme, which binds 165 identifiers.

        R4RS, which binds 150 essential identifiers and 31 non-essential
        ones for a total of 181.

        R5RS, which binds 185 required identifiers and 6 non-required
        ones for a total of 191.

        My proposal for R7RS small Scheme, which binds 182 identifiers
        in the core and 54 more in 16 feature groups, for a total of 236.

        R6RS, which binds 156 identifiers in the base library and
        506 more in 23 other libraries for a total of 662.

        ANSI CL, which binds 978 identifiers, 35 of which are
        bound in two namespaces and 2 in three namespaces, for
        a total of 1017 bindings.
