hey take up very little space and if they are reused often it's acceptable to compile them at boot and never release them. <div class='code_block'><span class='keyword'>local</span> re = <span class='keyword'>regexcompile</span>(<span class='string'>"([0-9]+)"</span>)
...
re = <span class='keyword'>regexfree</span>(re)
</div>By storing the <span class='inline_code'>null</span> return from <span class='inline_code'>regexrelease</span> it lower the risk that it will be used again after releasing. </div></div>
