Code Blocks Not Allowed in SharePoint 2010

Recently been doing some quick prototyping some web-parts, regular aspx, and master pages in sharepoint and just been using inline code blocks. then i got an error message as follows

 

"An error occurred during the processing of /_Path. Code blocks are not allowed in this file."

 

In order to work around this I had to edit the web.config  as follows.

 

<SharePoint>

  <SafeMode MaxControls="200" CallStack="false" DirectFileDependencies="10" TotalFileDependencies="50" AllowPageLevelTrace="false">

   <PageParserPaths>

 

  <PageParserPath VirtualPath="~/pages/*" CompilationMode="Always" AllowServerSideScript="true" />

    </PageParserPaths>

  </SafeMode>
