_D_e_s_c_r_i_p_t_i_o_n:

     '.Primitive' returns an entry point to a "primitive" (internally
     implemented) function.

     The advantage of '.Primitive' over '.Internal' functions is the
     potential efficiency of argument passing.

_U_s_a_g_e:

     .Primitive(name)

_A_r_g_u_m_e_n_t_s:

    name: name of the R function.

_S_e_e _A_l_s_o:

     '.Internal'.

_E_x_a_m_p_l_e_s:

     mysqrt <- .Primitive("sqrt")
     c
     .Internal # this one *must* be primitive!
     get("if") # just 'if' or 'print(if)' are not syntactically ok.
