load module

[Marc Stiegler]

This list is indeed for E-users as well. Someone else will have to answer
question 1, but the answer to question 2 is this: since E is typeless, you
are correct that E cannot reliably pick out which method/constructor to call
if there are multiple methods with signatures distinguished only by
parameter types.

To create a button with the single-string-parameter constructor, use

E call(<swing:JButton>, "new(String)", ["MyButton"])

You will find this, as well as other tricks, embedded in the eChat program
at

http://www.skyhunter.com/marc.html

The eChat program has been documented with an eye to being a part of the
introductory experience for new E programmers, though your usage of

interp evalPrint(e__quasiParser valueMaker(<file:module.e> getText))

as your solution for question 1 indicates you are in some ways far beyond
the point of being a beginner :-)
