constants are basically just sub FOO () { ... } (Constant Functions). So I first tried your @{ STEPPER_SEQUENCE }, but Perl reminded me: Ambiguous use of @{STEPPER_SEQUENCE} resolved to @STEPPER_SEQUENCE and Global symbol "@STEPPER_SEQUENCE" requires explicit package name. However, once you disambiguate:

use constant STEPPER_SEQUENCE => [ [qw(1 0 0 1)], [qw(1 0 0 0)], [qw(1 1 0 0)], [qw(0 1 0 0)], [qw(0 1 1 0)], [qw(0 0 1 0)], [qw(0 0 1 1)], [qw(0 0 0 1)], ]; print 0+@{STEPPER_SEQUENCE()}, "\n"; print 0+@{+STEPPER_SEQUENCE}, "\n"; print 0+@{&STEPPER_SEQUENCE}, "\n"; __END__ 8 8 8

Update: The thread constant vector might be relevant here too. Also added the third example, although note that calls to constant functions with & are not subject to inlining.

to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
