Test suite was sub()ifying argument to sumnuminit().
Test suite would not correctly sub()ify intnum() if limits had "()".
Test suite calculated Pi Euler too early; Now only these fail
t/55_intnum.t 51 1 1.96% 12
t/55_ploth.t 34 1 2.94% 4
# eval-noans: $oo=[ PARI(1) ];
# eval-noans: setprecision(96)
# eval-noans: $tab=intfuncinit($t,[-$oo,4.5],[$oo,4.5], sub{gamma(2+ I*$t)**3},1);
# eval: intmellininvshort(2,4,$tab)-$A

# pari==='-3.072350108 E-97 + 9.90717831 E-100*I'
# re_out='\-3\.072350108,?\s*E\-97,?\s*\+,?\s*9\.90717831,?\s*E\-100\*I'
Why this succeeds?
# eval: intnum($x,-1,1, sub{intnum($y,-sqrt(1-$x**2),sqrt(1-$x**2),$x**2+$y**2,$tab)},$tab)- Pi/2
Actually, $x**2+$y**2 is converted to a string as in '0.09+y^2',
which is interpreted by GP/PARI.
Add warnings to the test suite for detection of #@_
in Perl-in-PARI-in-Perl calls.
