=over =item goto LABEL =item goto EXPR =item goto &NAME The C form finds the statement labeled with LABEL and resumes execution there. It may not be used to go into any construct that requires initialization, such as a subroutine or a C loop. It also can't be used to go into a construct that is optimized away, or to get out of a block or subroutine given to C. It can be used to go almost anywhere else within the dynamic scope, including out of subroutines, but it's usually better to use some other construct such as C or C. The author of Perl has never felt the need to use this form of C (in Perl, that is--C is another matter). The C form expects a label name, whose scope will be resolved dynamically. This allows for computed Cs per FORTRAN, but isn't necessarily recommended if you're optimizing for maintainability: goto ("FOO", "BAR", "GLARCH")[$i]; The C form is highly magical, and substitutes a call to the named subroutine for the currently running subroutine. This is used by C subroutines that wish to load another subroutine and then pretend that the other subroutine had been called in the first place (except that any modifications to C<@_> in the current subroutine are propagated to the other subroutine.) After the C, not even C will be able to tell that this routine was called first. =back
