Hi, thank you

I've been trying to reproduce the error and I can do it by marking the array readonly

$ perl -e " use Data::Lock qw/ dlock /; use Devel::Peek; my @f;       
+  Dump\@f; dlock \@f; Dump\@f; $f[1]=1;   "

SV = IV(0x3f9ad8) at 0x3f9adc
  REFCNT = 1
  FLAGS = (TEMP,ROK)
  RV = 0x99bb0c
  SV = PVAV(0x3fa970) at 0x99bb0c
    REFCNT = 2
    FLAGS = (PADMY)
    ARRAY = 0x0
    FILL = -1
    MAX = -1
    ARYLEN = 0x0
    FLAGS = (REAL)

Modification of a read-only value attempted at -e line 1.

That split is somehow is marking it readonly is so weird :D

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.
