Setting environment variable crashes with posargs

Issue #355 on hold

created an issue

On tox 2.4.0.dev1:

[testenv]
setenv =
    ; works
    TOX_ENVNAME = {envname}
    TOX_TOXINIDIR = {toxinidir}
    TOX_TOXWORKDIR = {toxworkdir}
    ; crashes
    TOX_POSARGS = {posargs}

It works with all other variables as far as I can say, only with posargs it crashes with

    I just had a look in the code: posargs are treated differently from the other values which are called substitutions, that is why posargs does not turn up in the reader._subs dict, which is what is accessed, when setenv is being used. So I understand now, why the error occurs, but from my perspective as a user there is no reason, why {posargs} should behave differently than {envname} and why it shoud behave differently in setenv than somewhere else in tox.ini.
