LIMITATIONS: It is not possible to export globals starting with a period

[HenrikBengtsson]

It is not possible to export globals starting with a period, e.g.

> library(async)
> plan(batchjobs, backend="local")
> a <- 1
> x %<=% { 2 * a }
> x
[1] 2
> .b <- 2
> x %<=% { 2 * a * .b }
Error in asyncBatchEvalQ(reg, exprs = list(task$expr), envir = task$envir,  :
  BatchJobs does not support exported variables that start with a period
  (see https://github.com/tudo-r/BatchJobs/issues/103): '.b'

See tudo-r/BatchJobs#103 for troubleshooting and details.
