Enforce { } and replace use case with new statements?
=====================================================

from:
    if x continue
    if y return 123
    if z goto end

to:
    continue if x
    return 123 if y
    goto end if z
    # (perhaps "continue" should be renamed to "skip" or "next")
    # "return ...long expression... if ..." could be confusing

or:
    cskip if x
    creturn 123 if y
    cgoto end if z

or:
    when x skip
    when x return 123
    when x goto z
