Variable declarations specifically--that removes quite a few problems from
the parser implementation.  But, also, declarations and definitions of all
types, exception handling try and catch blocks, statements, etc..  I.e. it
leaves out most of the stuff that makes the parser complicated.  The
difficult part of the semantic analysis would still be lookup and
overloading, IMHO.
