NAME

Acme::SvGROW - syntax for pre-extending a string's storage, like the proposed use of length as an L-value

SYNOPSIS

  use Acme::SvGROW;
  SvGrow($BigString, 100000);
  # when l-value subroutines are available (5.8 and later)
  SvGrow($BigString, 100000) = InitialValueOfBigString();

DESCRIPTION

Trivial module implementing string storage preallocation using techniques shared on perl5-porters mailing list November 4 and 5, 2009

EXPORT

the SvGROW subroutine is exported. It takes two arguments, the first the string to extend and the second the length.

SEE ALSO

perlguts

Data::Peek for a benchmarking of the alternatives

The author of this module is in favor of allowing length to be used as an lvalue to thinly invoke the SvGROW internals macro
