subs - Perl pragma to predeclare sub names
SSSSYYYYNNNNOOOOPPPPSSSSIIIISSSS
use subs qw(frob);
frob 3..10;
DDDDEEEESSSSCCCCRRRRIIIIPPPPTTTTIIIIOOOONNNN
This will predeclare all the subroutine whose names are in the list,
allowing you to use them without parentheses even before they're
declared.
Unlike pragmas that affect the $^H hints variable, the use vars and use
subs declarations are not BLOCK-scoped. They are thus effective for the
entire file in which they appear. You may not rescind such declarations
with no vars or no subs.
See the section on _P_r_a_g_m_a_t_i_c _M_o_d_u_l_e_s in the _p_e_r_l_m_o_d manpage and the
section on _s_t_r_i_c_t _s_u_b_s in the _s_t_r_i_c_t manpage.
