syntax of repeated conditionals?

Hi Experts, 

I'm new to powershell and wondering why this throws an error :

$all =[long] [Microsoft.SqlServer.Management.Smo.DatabaseObjectTypes]::Table `
        -bor [Microsoft.SqlServer.Management.Smo.DatabaseObjectTypes]::View
        -bor [Microsoft.SqlServer.Management.Smo.DatabaseObjectTypes]::StoredProcedure
        -bor [Microsoft.SqlServer.Management.Smo.DatabaseObjectTypes]::UserDefinedFunction
        -bor [Microsoft.SqlServer.Management.Smo.DatabaseObjectTypes]::Schema

But this does not:

$all =[long] [Microsoft.SqlServer.Management.Smo.DatabaseObjectTypes]::Table `
        -bor [Microsoft.SqlServer.Management.Smo.DatabaseObjectTypes]::View  -bor [Microsoft.SqlServer.Management.Smo.DatabaseObjectTypes]::StoredProcedure -bor [Microsoft.SqlServer.Management.Smo.DatabaseObjectTypes]::UserDefinedFunction -bor [Microsoft.SqlServer.Management.Smo.DatabaseObjectTypes]::Schema

Also, is there an equivalent to this (SQL)?  

where DatabaseObjectTypes in ('Table','View','Stored Procedure', 'UserDefinedFunction','Synonym')

Thanks in advance!
