#1705: 0-args :main Subs will check passed arguments.

Reporter: bacek | Owner:
Type: deprecation | Status: new

-------------------------+--------------------------------------------------
After 2.6 we'll enable check arguments of 0-args Subs which can break
current :main Sub invocation.
For example
{{{
.sub "foo" :main
say "Hello world"
.end
}}}
will throw an exception if command-line arguments passed.
For updating from current behaviour :main Sub should declare {{{.param pmc
args :slurpy}}} to work with any numbers of arguments.
See also #1033 for original "0-args Subs" ticket.
