Naive file length enforcement before build

Some.targets

<Project>
  <Target Name="DubiksCube" BeforeTargets="Build">
    <PropertyGroup>
      <DubiksLimit>42</DubiksLimit>
    </PropertyGroup>
    <ItemGroup>
      <FilesWithNames Include="@(Compile)" NameLength="$([System.String]::new('%(Identity)').Length)" />
      <FilesWithTooLongNames Include="@(FilesWithNames)" Condition="%(NameLength) &gt; $(DubiksLimit)" />
    </ItemGroup>
    <Error Condition="'@(FilesWithTooLongNames->Count())' &gt; 0" Text="These file names are too long: @(FilesWithTooLongNames)" />
  </Target>
</Project>
