  Returns whether the SpringEL compiler should be enabled in SpringEL expressions or not.
  </p>
  <p>
  (This is just a convenience method, equivalent to calling
  {@link SpringStandardDialect#getEnableSpringELCompiler()} on the dialect instance itself. It is provided
  here in order to allow users to enable the SpEL compiler without
  having to directly create instances of the {@link SpringStandardDialect})
  </p>
  <p>
  Expression compilation can significantly improve the performance of Spring EL expressions, but
  might not be adequate for every environment. Read
  <a href="http://docs.spring.io/spring/docs/current/spring-framework-reference/html/expressions.html#expressions-spel-compilation">the
  official Spring documentation</a> for more detail.
  </p>
  <p>
  Also note that although Spring includes a SpEL compiler since Spring 4.1, most expressions
  in Thymeleaf templates will only be able to properly benefit from this compilation step when at least
  Spring Framework version 4.2.4 is used.
  </p>
  <p>
  This flag is set to {@code false} by default.
  </p>
  
  @return {@code true} if SpEL expressions should be compiled if possible, {@code false} if not.
