Document Classes ⇒ Beamer: Block width?

[guest75]

Hi Stefan,

Hi Tom,

I took it from the original block environment code which is: (...)
Based on this I created the modified variable environment above. So the only reason for me was to use the same code for consistency.

Ok.

Yes, LaTeX users should use \renewcommand which is higher level and safer. Package programmers use \def because it's faster. For user code, safety is more important than speed.

Ok. But \renewcommand doesn't seem to work in this situation.
