* but excluding certain files

I'd like to do something like

cat *

but which would ignore files that match the pattern __*__.

What's the best way to do this?

From my today's answer for similar question

ls --ignore="__*__" --quoting-style=shell | xargs cat

If you enable extglob in bash (shopt -s extglob), you can use 

cat !(excluded_file|excluded_*_pattern)

extglob patterns:

| 
    or/alternatives
?(pattern-list)
    Matches zero or one occurrence of the given patterns
*(pattern-list)
    Matches zero or more occurrences of the given patterns
+(pattern-list)
    Matches one or more occurrences of the given patterns
@(pattern-list)
    Matches one of the given patterns
!(pattern-list)
    Matches anything except one of the given patterns

Perhaps not the best way, but:

tcsh -c 'echo ^__*__'
