Take this minimal example where we ask for information on the "math.subtract" op in Jython from the Fiji script editor:

# get op environoment
from org.scijava.ops.api import OpEnvironment
ops = OpEnvironment.getEnvironment()

print(ops.descriptions("math.subtract"))

This produces the following output:

[math.subtract(
	 Inputs:
		I1 input1
		I2 input2
	 Containers (I/O):
		O result
)
, math.sub(
	 Inputs:
		java.lang.Number input1
		java.lang.Number input2
	 Outputs:
		java.lang.Double output1
)
Aliases: [math.subtract]
]

What types are the input (I1 and I2) and output (O)? After talking to Gabe, I learned they are RealTypes. The output from ops.descriptions() does not indicate that these are RealTypes. How can we display the parameter types here?
