i guess there's no way to *conditionally* add tasks?

[Robert P. J. Day]

  digging into ptest stuff, and i notice this in ptest.bbclass:

addtask configure_ptest_base after do_configure before do_compile
addtask compile_ptest_base   after do_compile   before do_install
addtask install_ptest_base   after do_install   before do_package do_populate_sysroot

python () {
    if not bb.data.inherits_class('native', d) and not bb.data.inherits_class('cross', d):
        d.setVarFlag('do_install_ptest_base', 'fakeroot', 1)

    # Remove all '*ptest_base' tasks when ptest is not enabled
    if not(d.getVar('PTEST_ENABLED', True) == "1"):
        for i in ['do_configure_ptest_base', 'do_compile_ptest_base', 'do_install_ptest_base']:
            bb.build.deltask(i, d)
}

  so i'm guessing there's no way to conditionally add task(s) to avoid
adding them, only to turn around and delete them, yes?

I solved similar issues by including files conditionally; e.g. above
would be

---
ptest_inc = "${@['noop', 'ptest'][d.getVar('PTEST_ENABLED', True) == '1']}"
include ptest-${ptest_inc}.inc

--- ptest-ptest.inc ---
addtask configure_ptest_base after do_configure before do_compile
addtask compile_ptest_base   after do_compile   before do_install
addtask install_ptest_base   after do_install   before do_package
do_populate_sysroot

The point is most of the time you shouldn't need to do this kind of thing 
anymore since the introduction of addtask/deltask python functions.
