> Matrix and frame right indexing is subject to rewrites, where we simplify for
> example {{X[,a]}} to {X}} if the input and output have equal sizes. This
> rewrite is, however, only valid if the index ranges are valid. We do throw
> validation errors during parsing, but this does not apply to matrices and
> index expressions that are unknown during initial compilation.
> For, example the below expressions computes 1000 although it should throw an
> error:
> {code}
> X = matrix(1, 1000, 1);
> if( 0!=0 )
> X = cbind(X,X);
> print(sum(X[,2]))
> {code}
